Abstract: The structural, elastic, electronic, and magnetic properties of the CrCoSi, MnCoSi parent half-Heusler (HH) alloys, and their CrMn[Co.sub.2][Si.sub.2] derivative double half-Heusler (DHH) compound are studied, utilizing the augmented plane wave method, which is based on density functional theory and implemented in the WIEN2k code. The stability of HH structure of the CrCoSi and MnCoSi alloys has been checked for their non-magnetic and ferromagnetic phases, leading to that the latter phase of the type I arrangement is the most stable. The CrMn[Co.sub.2][Si.sub.2] DHH alloy, derivative from the found structural and magnetic ground states of CrCoSi and MnCoSi HH alloys, is constructed and investigated. This DDH as well as its CrCoSi parent HH are found to be resistant to deformation and can be classified as ductile materials, whereas the MnCoSi compound is brittle. By the gradient generalized approximation (GGA), the electronic structures of CrCoSi, MnCoSi, and CrMn[Co.sub.2][Si.sub.2]compounds exhibit a metallic behavior in the spin-up channel and a semiconducting behavior in the spin-dn channel, with band gaps (half-metallic gaps) of 0. 851(0.020), 0.852(0.021), and 0.531(0.002) eV, respectively. The half-metallicity of CrMn[Co.sub.2][Si.sub.2] DHH is retained with smaller (larger) band gap (half-metallic gap) of 0.38(0.106) eV than that of GGA, using GGA + U approximation. In addition, the total magnetic moments are found to be 1, 2, and 3 [[mu].sub.B] for CrCoSi, MnCoSi, and CrMn[Co.sub.2][Si.sub.2], respectively. Therefore, these alloys can be good candidates for spinitronic applications due to their half-metallicity. Key words: half-metal, heusler alloys, spin polarization, mechanical stability, FP-LAPW, 1. Introduction Spin-based electronics has grown into a significant field of study that spans a wide range of high spin-polarized materials, used in spintronic devices. It overcomes the limitations of [...]

2. Theoretical investigation on tautomerism and NLO properties of salicylideneaniline derivatives

Author: Daho, N., Benhalima, N., Khelfaoui, F., Sadouki, O., Elkeurti, M., and Akil, Z.
Subjects: Tautomers -- Chemical properties, Aniline -- Chemical properties, Physics
Abstract: In this work, a comprehensive investigation of the salicylideneaniline derivatives is carried out using density functional theory to determine their linear and nonlinear optical (NLO) properties. Geometry optimizations, for gas and solvent phases, of the tautomers (enol and keto forms) are calculated using B3LYP levels with 6-31G(d,p) basis set. An intramolecular proton transfer, for 1SA-E and 2SA-E, is performed by a PES scan process at the B3LYP/6-31G(d,p) level. The optical properties are determined and show that they have extremely high NLO properties. In addition, the RDG analysis, molecular electrostatic potential (MEP), and gap energy are calculated. The low energy gap value indicates the possibility of intramolecular charge transfer. The frontier molecular orbital calculations clearly show the inverse relationship of HOMO-LUMO gap with the first-order hyperpolarizability ([beta] = 59.6471 * [10.sup.-30] esu), confirming that the salicylideneaniline derivatives can be used as attractive future NLO materials. Therefore, the reactive sites are predicted using MEP and the visible absorption maxima are analyzed using a theoretical UV-Vis spectrum. Natural bond orbitals are used to investigate the stability, charge delocalization, and intramolecular hydrogen bond. Key words: first hyper polarizability, HOMO-LUMO energy gap, NLO properties, UV-Vis spectrum, tautomers. Nous completons ici une investigation des derives de salicylideneaniline en utilisant la theorie de la fonctionnelle de densite, afin de determiner leurs proprietes optiques lineaires et non lineaires. Nous calculons l'optimisation geometrique des tautomeres (dans les formes eno (eno) et ceto (keto)), pour les phases gazeuse et solute, en utilisant les niveaux B3YLP et l'ensemble de base 6-31G(d,p). Un transfert intramoleculaire, pour 1SA-E et 2SA-E, est verifie par balayage de l'energie potentielle de surface (EPS/PES) au niveau B3LYP/6-3G(d,p). Nous determinons les proprietes optiques des echantillons et montrons qu'elles sont extremement non lineaires. De plus, l'analyse du Gradient de Densite Reduite (GDR/RDG), le potentiel electrostatique moleculaire (PEM/MEP) et le gap d'energie sont aussi evalues. La faible valeur du gap d'energie indique la possibilite d'un transfert de charge intramoleculaire. Le calcul de l'orbitale moleculaire frontiere montre clairement l'inversion du gap HOMO-LUMO avec une hyperpolarisabilite ([beta] = 59.6471 * [10.sup.-30] esu), confirmant que les derives de salicylideneaniline peuvent etre utilises comme d'interessants materiaux en optique non lineaire (ONL/NLO). Par consequent, nous identifions les sites reactifs en utilisant le PEM et les maxima d'absorption dans le visible sont analyses via le spectre theorique UV-Vis. Les orbitales liees localisees (naturelles) sont utilisees pour analyser la stabilite, la delocalisation de charge et le lien hydrogene intramoleculaire. Mots-cles : premiere super polarisabilite, gap d'energie HOMO-LUMO, proprietes d'optique non lineaire, spectre UV-Vis, tautomeres., 1.

5. Effect of physical and mechanical parameters on the reflected signal from the first interface of human cancellous bone—application of Biot's theory

Author: Fatima Zahra Hamadouche and Mustapha Sadouki
Subjects: Physics, Acoustics and Ultrasonics, Characteristic length, Biot number, Mathematical analysis, Tortuosity, Signal, symbols.namesake, Fourier transform, Arts and Humanities (miscellaneous), Frequency domain, symbols, Time domain, Reflection coefficient
Abstract: In this work, a simulated study on the effects of physical and mechanical parameters describing human cancellous bone on reflected ultrasound waves is proposed. The visco-inertial exchanges between the structure and the saturating fluid are described by the Biot theory modified by the Johnson model. A simplified expression of the reflection coefficient at the first interface is obtained in the frequency domain. This expression depends on three physical parameters which are porosity, tortuosity, and viscous characteristic length as well as the mechanical parameters; Young's modulus and Poisson's ratio. The reflected signal is calculated in the frequency domain by the product of the spectrum of the incident signal with the reflection coefficient. In the time domain, the reflected wave is obtained by taking the inverse Fourier transform of the reflected frequency signal. The effect of each parameter on the reflected signal is studied. The results obtained are discussed and compared with those given in the literature.

6. Experimental characterization of air-saturated porous material via low-frequencies ultrasonic transmitted waves

Abstract: An improved acoustic method is proposed for measuring the tortuosity and the viscous and thermal characteristic lengths of air-saturated porous materials via low-frequency ultrasonic transmitted waves (70 kHz–110 kHz). The equivalent fluid model is considered. The interaction between the saturated fluid and the structure is taken into account in two frequency response factors: the dynamic tortuosity of the medium and the dynamic compressibility of the air which are described by their high-frequency expansion in powers of the viscous and thermal skin depth, either limiting the expansion to the first two leading terms or the first three leading terms with the introduction of two new viscous and thermal shape factors. These two new factors play an important role in stabilizing and improving the inverted parameters of the tortuosity and the viscous and thermal characteristic lengths in the frequency band considered. The inverse problem is solved numerically in the frequency domain by minimizing the spectrum of simulated and experimental transmitted signals. Optimized parameters of tortuosity, viscous and thermal characteristic lengths, and viscous and thermal shape factors are obtained simultaneously. The tests are carried out with three samples of plastic foam. The results obtained by the two procedures are discussed and compared to those given in the literature.

Abstract: The inclusive production of charmed particles in Z--> decays has been measured from the yield of D-0, D+, D-s(+) and Lambda(c)(+) decays in a sample of events with high b purity collected with the ALEPH detector from 1992 to 1995. From these measurements, adding the charmonia production rate and an estimate of the charmed strange baryon contribution, the average number of charm quarks per b decay is determined to be n(c)=1.230+/-0.036+/-0.038+/-0.053, where the uncertainties are due to statistics, systematic effects and branching ratios, respectively.

Abstract: Searches for supersymmetric particles produced in e(+)e(-) collisions at centre-of-mass energies of 130 and 136 GeV have been performed in a data sample of 5.7 pb(-1) collected in the autumn of 1995 by the ALEPH detector at LEP. No candidate events were found, allowing limits to be set on the masses and production cross-sections of scalar leptons, scalar tops, charginos and neutralinos. The domains previously excluded at LEP1 are substantially extended. For instance, masses of gaugino-like charginos smaller than 67.8 GeV/c(2) are excluded at the 95% C.L. for scalar neutrino masses larger than 200 GeV/c(2).

Abstract: From a study of the kinematic properties of the final state produced in the semileptonic decays ${\rm b\to X\ell\nu_{\ell}}$ , the inclusive charmless semileptonic branching ratio of b hadrons is measured. With a sample of 3.6 million hadronic Z decays recorded between 1992 and 1995 with the ALEPH detector at LEP, the value ${\rm Br(b\to X_u\ell\nu_{\ell})}$ is determined to be $(1.73\pm 0.55_{{\rm stat}}\pm 0.55_{{\rm syst}})\times 10^{-3}$ , where ${\rm X_u}$ represents any charmless hadronic state and b is a mixture of b hadrons weighted by their production rates. This measurement yields the result \[ {\rm |V_{ub}|^2}= (18.68\pm 5.94_{{\rm stat}}\pm 5.94_{{\rm syst}}\pm 1.45_{HQE})\times 10^{-6}, \] where the last error comes from the conversion of the branching ratio to the CKM matrix element squared.

Abstract: The full statistics of hadronic Z decays collected with the ALEPH detector are analysed to measure, by three methods, the ratio, ${\rm R_c}$ , of the partial decay width of the Z into ${\rm c\bar c}$ quarks to the total hadronic width. One method uses the inclusive $p$ and $p_{\perp}$ spectra of electrons. The other two use a double-tagging technique to measure ${\rm R_c}$ independently of the charm-tagging efficiency. In one, the tagging procedure uses the reconstruction of high momentum charmed mesons ( ${\rm D^{*+}}$ , ${\rm D^+}$ and ${\rm D^0}$) to detect the charm quarks. In the other, a charm quark is tagged from the ${\rm D^*}$ 's reconstructed in the ${\rm D^{*+} \to \pi^+ D^0}$ decay channel and the other from the slow pion from the ${\rm D^{*-} \to \pi^- \bar{D}^0}$ decay. The combination of these measurements leads to ${\rm R_c = \Gamma(Z \to c\bar c) / \Gamma(Z \to hadrons)}) = 0.1681\pm0.0054({\rm stat})\pm0.0062({\rm syst})$ .

Abstract: From a sample of about 160k $\mbox{Z}\!\!\to\!\!\tau^+\tau^-$ candidates collected with the ALEPH detector at LEP between 1991 and 1995, $\tau$ lepton decays involving $K^0_S\!\to\!\pi^+\pi^-$ are studied. The $K^0_SK^0_L$ associated production in $\tau$ decays is also investigated. The branching ratios are measured for the inclusive decay $B(\tau^-\!\!\to\!\!K^0_SX^-\nu_\tau)=(9.70\!\pm\!0.58\!\pm\!0.62)\ times10^{-3}$ , where $X^-$ can be anything, and for the exclusive decays \begin{center} \begin{tabular}{rcl} $B(\tau^-\!\!\to\!\!\overline{K}^0\pi^-\nu_\tau)$&=&$(8.55\!\pm\!1. 17\! \pm\!0.66)\times10^{-3}$,\\ $B(\tau^-\!\!\to\!\!\overline{K}^0\pi ^-\pi^0\nu_\tau)$&=&$(2.94\!\pm\! 0.73\!\pm\!0.37)\times10^{-3}$, \\ $B(\tau^-\!\!\to\!\!\overline{K} ^0K^-\nu_\tau)$&=&$(1.58\!\pm\!0.42\!\pm\! 0.17)\times10^{-3}$, \\ $B(\tau^-\!\!\to\!\!\overline{K}^0K^-\pi^0\nu_\tau)$&=&$(1.52\!\pm\ !0.76\! \pm\!0.21)\times10^{-3}$. \\ \end{tabular} \end{center} The decays $\tau^-\!\!\to\!\!K^0_SK^0_L\pi^-\nu_\tau$ is studied for the first time, giving a branching ratio \begin{center} \begin{tabular}{rcl} $B(\tau^-\!\!\to\!\!K^0_SK^0_L\pi^-\nu_\tau)$&=&$ (1.01\!\pm\!0.23\!\pm\!0.13)\times10^{-3}.$ \end{tabular} \end{center} The channels $\tau^-~\!\!\!\to\!\!\!~K^0_SK^0_S\pi^-\nu_\tau~$, $\tau^-~\!\!\!\to\!\!\!~K^0_SK^0_S\pi^-\pi^0\nu_\tau~$, $\tau^-~\!\!\!\to\!\!\!~K^0_SK^0_L\pi^-\pi^0\nu_\tau~$, $\tau^-~\!\!\!\to\!\!\!~\overline{K}^0\pi^-\pi^0\pi^0\nu_\tau$, $\tau^-~\!\!\!\to\!\!\!~K^0K^-\pi^0\pi^0\nu_\tau$ and $\tau^-~\!\!\!\to\!\!\!~K^0h^+h^-h^-\nu_\tau$ are also investigated. In addition, mass spectra in the $K^0_Sh^-$ and $K^0_Sh^-\pi^0$ final states are analysed to provide information on the intermediate states produced in the decays.

Abstract: Two samples of exclusive semileptonic decays, 579 B0 -> D*+l-νl events and 261 B0 -> D+l-νl events, are selected from approximately 3.9 million hadronic Z decays collected by the ALEPH detector at LEP. From the reconstructed differential decay rate of each sample, the product of the hadronic form factor F(ω) at zero recoil of the D(*)+ meson and the CKM matrix element Vcb are measured to be FD*+ (1) Vcb = (31.9 +/- 1.8stat +/- 1.9syst) × 10-3,FD+ (1) Vcb = (27.8 +/- 6.8stat +/- 6.5syst) × 10-3. The ratio of the form factorsFD+ (1) and FD*+ (1) is measured to beFD+ (1)/FD*+ (1) = 0.87 +/- 0.22stat +/- 0.21syst. A value of Vcb is extracted from the two samples, using theoretical constraints on the slope and curvature of the hadronic form factors and their normalization at zero recoil, with the result Vcb = (34.4 +/- 1.6stat +/- 2.3syst +/- 1.4th) × 10-3. The branching fractions are measured from the two integrated spectra to be Br(B0 -> D*+l-νl) = (5.53 +/- 0.26stat +/- 0.52syst) %, Br(B0 -> D+l-νl) = (2.35 +/- 0.20stat +/- 0.44syst) %.

Abstract: Using data obtained with the ALEPH detector at the Z resonance, a measure based on transverse momentum is shown to exhibit a correlation between the two halves of a hadronic event which cannot be explained by energy-momentum conservation, flavour conservation, the imposition of an event axis or imperfect event reconstruction. Two possible interpretations based on existing Monte Carlo models are examined: a) ARIADNE, with the correlation forming early in the parton shower and with the transition from partons to hadrons playing only a minor part; b) JETSET, with the correlation forming at the fragmentation stage. A correlation technique based on a jet cluster analysis is used to make a comparison of the models with the data. It is concluded that both non-perturbative and perturbative effects make important contributions to the observed correlation.

Abstract: Previously published and as vet unpublished QCD results obtained with the ALEPH detector at LEP1 are presented. The unprecedented statistics allows detailed studies of both perturbative and non-perturbative aspects of strong interactions to be carried out using hadronic Z and tau decays. The studies presented include precise determinations of the strong coupling constant. tests of its flavour independence, tests of the SU(3) gauge structure of QCD, study of coherence effects, and measurements of single-particle inclusive distributions and two-particle correlations for many identified baryons and mesons.

Abstract: Final states with charged kaons in three-prong τ decays are studied by exploiting the particle identification from the dE/dx measurement. The results are based on a sample of about 1.6 × 105 detected τ pairs collected with the ALEPH detector between 1991 and 1995 around the Z peak. The following branching ratios have been measured: B(τ- → K−K+π−ντ) = (1.63 ± 0.21 ± 0.17) × 10−3, B(τ− → K−π+π−ντ) = (2.14 ± 0.37 ± 0.29) × 10−3, B(τ− → K−K+π−π0ντ) = (0.75 ± 0.29 ± 0.15) × 10−3, and B(τ− → K−π+π−π0ντ) = (0.61 ± 0.39 ± 0.18) × 10−3. The first two measurements are more precise than the current world averages, while the last two channels are investigated for the first time. The 95% C.L. upper limit on the branching ratio for the decay τ− → K−K+K−ντ is 0.19 × 10−3. A study of intermediate states occurring in the K−K+π−ντ and K−π+π−ντ decays is also presented. Final states with charged kaons in three-prong τ decays are studied by exploiting the particle identification from the dE/dx measurement. The results are based on a sample of about 1.6 x 105 detected τ pairs collected with the ALEPH detector between 1991 and 1995 around the Z peak. The following branching ratios have been measured: B(τ- → K-K+π-ντ) = (1.63 ± 0.21 ± 0.17) x 10-3, B(τ- → K-π+π-ντ)=(2.14 ± 0.37 ± 0.29) x 10-3, B (τ- → K-K+π-π0ντ) = (0.75 ± 0.29 ± 0.15) x 10-3, and B(τ- → K-π+π-π0ν τ) = (0.61 ± 0.39 ± 0.18) x 10-3.

Abstract: The data collected by the ALEPH experiment at LEP at centre-of-mass energies around 183 GeV are analysed to search for sleptons, the partners of leptons in supersymmetric theories. The previously published search for acoplanar leptons and missing energy has been updated. New searches have been developed to cover a wider range of slepton signals. These include single electrons, acoplanar leptons accompanied by two photons plus missing energy as well as particles with lifetime. No evidence for the production of any such particles is found. Slepton mass limits are reported within gravity mediated and gauge mediated SUSY breaking scenarios. (C) 1998 Elsevier Science B.V. All rights reserved.

Abstract: An improved measurement of the forward-backward asymmetry in Z --> b (b) over bar decays is presented, based on a sample of 4.1 million hadronic Z decays collected by ALEPH between 1991 and 1995. Data are analysed as a function of polar angle of the event axis and b purity. The event tagging efficiency and mean b-jet hemisphere charge are measured directly from data. From the measured forward-backward jet charge asymmetry, the b quark asymmetry at root s= m(Z) is determined to be: A(FB)(b) = 0.1017 +/- 0.0032(syst.) +/- 0.0032(syst.). In the context of the Standard Model this corresponds to a value of the effective weak mixing angle of sin(2) theta(W)(eff)= 0.23109 +/- 0.00096.

Abstract: The production of final states involving one or more energetic photons from e(+)e(-) collisions is studied in a sample of 58.5 pb(-1) of data recorded at a centre-of-mass energy of 183 GeV by the ALEPH detector at LEP. The e(+)e(-) --> v (v) over bar gamma(gamma) and e(+)e(-) --> gamma gamma(gamma) cross sections are measured. The data are in good agreement with predictions based on the Standard Model and are used to set upper limits on the cross sections for anomalous photon production in the context of two supersymmetric models and for various extensions to QED. In particular, in the context of a super-light gravitino model a cross section upper limit of 0.38 pb is placed on the process e(+)e(-) --> (G) over tilde (G) over tilde gamma, allowing a lower limit to be set on the mass of the gravitino. Limits are also set on the mass of the lightest neutralino in Gauge Mediated Supersymmetry Breaking models. In the case of equal ee *gamma and ee gamma couplings a 95% C.L. lower limit on M-e* of 250 GeV/c(2) is obtained. (C) 1998 Published by Elsevier Science B.V. All rights reserved.

Abstract: Searches for scalar top and bottom quarks have been performed with data collected by the ALEPH detector at LEP. The data sample consists of 21.7 pb^-1 taken at sqrt{s} = 161, 170, and 172~GeV and 5.7 pb^-1 taken at sqrt{s} = 130 and 136~GeV. No evidence for scalar top quarks or scalar bottom quarks was found in the channels stop --> c chi, stop --> b l snu, and sbottom --> b chi. For the channel stop --> c chi a limit of 67 GeV/c^2 has been set on the scalar top quark mass, independent of the mixing angle between the supersymmetric partners of the left and right-handed states of the top quark. This limit assumes a mass difference between the stop and the chi of at least 10 GeV/c^2. For the channel stop --> b l snu the mixing-angle independent scalar top limit is 70 GeV/c^2, assuming a mass difference between the stop and the snu of at least 10 GeV/c^2. For the channel sbottom --> b chi, a limit of 73 GeV/c^2 has been set on the mass of the supersymmetric partner of the left-handed state of the bottom quark. This limit is valid if the mass difference between the sbottom and the chi is at least 10 GeV/c^2., Latex (epsfig): 16 pages including 6 figures

Abstract: In June 1996, the LEP centre-of-mass energy was raised to 161 GeV. Pair production of W bosons in e(+)e(-) collisions was observed for the first time by the LEP experiments. An integrated luminosity of 11 pb(-1) was recorded in the ALEPH detector, in which WW candidate events were observed. In 6 events both Ws decay leptonically. In 16 events, one W decays leptonically, the other into hadrons. In the channel where both Ws decay into hadrons, a signal was separated from the large background by means of several multi-variate analyses. The W pair cross-section is measured to be sigma(ww) = 4.23 +/- 0.73(stat.) +/- 0.19(syst.) pb. From this cross-section, the W mass is derived within the framework of the Standard Model: m(w) = 80.14 +/- 0.34(stat.) +/- 0.09(syst.) +/- 0.03(LEP energy) GeV/c(2) (C) 1997 Published by Elsevier Science B.V.

Abstract: The data recorded by the ALEPH experiment at LEP at centre-of-mass energies of 161 GeV and 172 GeV were analysed to search for sleptons, the supersymmetric partners of leptons. No evidence for the production of these particles was found. The number of candidates observed is consistent with the background expected from four-fermion processes and gammagamma-interactions. Improved mass limits at 95% C.L. are reported., Comment: 17 pages, 3 figures, submitted to Phys. Lett. B

Abstract: A search for the B-c meson decaying into the channels J/psi pi(+) and J/psi l(+)nu(l) (l = e or mu) is performed in a sample of 3.9 million hadronic Z decays collected by the ALEPH detector. This search results in the observation of 0 and 2 candidates in each of these channels, respectively, while 0.44 and 0.81 background events are expected. The following 90% confidence level upper limits are derived: Br(Z --> BcX)/Br(Z --> q (q) over bar BR(B-c(+) --> J/psi pi(+)) < 3.6 x 10(-5), Br(Z --> BcX)/Br(Z-->q (q) over bar)Br(B-c(+) --> J/psi l(+)nu) < 5.2 x 10(-5). Another B-c(+) --> J/psi(e(+)e(-))mu(+)nu(mu) candidate with very low background probability, found in an independent analysis, is also described in detail.

Abstract: A measurement of R-b using five mutually exclusive hemisphere tags has been performed by ALEPH using the full LEP1 statistics. Three tags are designed to select the decay of the Z(0) to b quarks, while the remaining two select Z(0) decays to c and light quarks, and are used to measure the tagging efficiencies. The result, R-b = 0.2159 +/- 0.0009(stat) +/-0.0011(syst), is in agreement with the electroweak theory prediction of 0.2158 +/- 0.0003. (C) 1997 Published by Elsevier Science B.V.

Abstract: The e(+)e(-) --> W+W- cross section is measured in a data sample collected by ALEPH at a mean centre-of-mass energy of 172.09 GeV, corresponding to an integrated luminosity of 10.65 pb(-1). Cross sections are given for the three topologies, fully leptonic, semi-leptonic and hadronic of a W-pair decay. Under the assumption that no other decay modes are present, the W-pair cross section is measured to be 11.7 +/- 1.2(stat.) +/- 0.3(syst.) pb. The existence of the triple gauge boson vertex of the Standard Model is clearly preferred by the data. The decay branching ratio of the W boson into hadrons is measured to be B(W --> hadrons) = 67.7 +/- 3.1(stat.) +/- 0.7(syst.) %, allowing a determination of the CKM matrix element \V-cs\ = 0.98 +/- 0.14(stat.) +/- 0.03(syst.).

Abstract: The process e(+)e(-) --> hA is used to search for the Higgs bosons of the Minimal Supersymmetric Standard Model (MSSM), in the b (b) over bar b (b) over bar and tau(+)tau(-)b (b) over bar final states, The search is performed in the data collected by the ALEPH experiment at LEP, at centre-of-mass energies between 130 and 172 GeV and with a total luminosity of 27.2 pb(-1). No candidate events are found in either of the final states, in agreement with the expected background of 0.91 events from all Standard Model processes. Combined with searches for e(+)e(-) --> hZ, this results in a 95% C.L. lower limit on the masses of both h and A of 62.5 GeV/c(2), for tan beta > 1. (C) 1997 Elsevier Science B.V.

Abstract: A search for pair-production of long-lived, heavy, singly-charged particles has been performed with data collected by the ALEPH detector at a centre-of-mass energy of 172 GeV. Data at \sqrt{s} = 161, 136, and 130 GeV are also included to improve the sensitivity to lower masses. No candidate is found in the data. A model-independent 95% confidence level upper limit on the production cross section at 172 GeV of 0.2-0.4pb is derived for masses between 45 and 86 GeV/c^2. This cross section limit implies, assuming the MSSM, a lower limit of 67 (69) GeV/c^2 on the mass of right- (left-) handed long-lived scalar taus or scalar muons and of 86 GeV/c^2 on the mass of long-lived charginos., Comment: 16 pages including 4 eps figures.

Abstract: Four candidates for charmless hadronic B decay are observed in a data sample of four million hadronic Z decays recorded by the ALEPH detector at LEP. The probability that these events come from background sources is estimated to be less than 10(-6). The average branching of weakly decaying B hadrons (a mixture of B-d(0), B-s(0) and Lambda(b) weighted by their production The average branching ratio of weakly decaying B hadrons (a mixture of B-d(0) cross sections and lifetimes, here denoted B) into two long-lived charged hadrons (pions, kaons or protons) is measured to be Br(B-->h(+)h(-))=(1.7(-0.7)(+1.0)+/-0.2)x10(-5). The relative branching fraction Br(B-d(s)(0)-->pi(+)pi(-)(K-))/Br(B-d(s)(0)-->h(+)h(-)) is measured to be 1.0(-0.3-0.1)(+0.0+0.0). In addition, branching ratio upper limits are obtained for a variety of exclusive charmless hadronic two-body decays of B hadrons.

Abstract: In a data sample of approximately four million hadronic Z decays recorded with the ALEPH detector from 1990 to 1995, a search for the strange b baryon Ξb is performed with a study of Ξ-lepton correlations. Forty-four events with same sign Ξ−l− combinations are found whereas 8.4 are expected based on the rate of opposite sign Ξ−l+ combinations. This significant excess is interpreted as evidence for Ξb semileptonic decays. The measured product branching ratio is Br(b → Ξ b ) × Br(Ξ b → X c Xl − ν l ) × Br(X c → Ξ − X′) = (5.4±1.1(stat) ± 0.8(syst)) × 10 −4 per lepton species, averaged over electrons and muons, with Xc a charmed baryon. The Ξb lifetime is measured to be τΞb = 1.35−0.28+0.37(stat)−0.17+0.15(syst) ps.

Abstract: Indirect limits on the mass of the lightest neutralino are derived from the results of searches for charginos, neutralinos, and sleptons performed with data taken by the ALEPH Collaboration at centre-of-mass energies near the Z peak and at 130 and 136 GeV. Within the context of the Minimal Supersymmetric Standard Model and when $M_{\tilde\nu}\ge 200$ GeV/c^2, the bound $M_\chi>12.8$ GeV/c^2 at the 95\% confidence level applies for any $\tan\beta$. The impact of lighter sneutrinos is presented in the framework of SUSY grand unified theories; a massless neutralino is allowed only for a narrow range of $\tan\beta$, $\mu$, and the scalar mass parameter $m_0$. Finally, by including Higgs mass constraints and requiring that radiative electroweak symmetry breaking occur, more stringent bounds on $M_\chi$ as a function of $\tan\beta$ are derived., Comment: 26 pages, one latex file and 15 eps figures

Abstract: Quark and gluon jets with the same energy, 24 GeV, are compared in symmetric three-jet configurations from hadronic Z decays observed by the ALEPH detector. Jets are defined using the Durham algorithm. Gluon jets are identified using an anti-tag on b jets, based on a track impact parameter method. The comparison of gluon acid mixed flavour quark jets shows that gluon jets have a softer fragmentation function, a larger angular width and a higher particle multiplicity. Evidence is presented which shows that the corresponding differences between gluon and b jets are significantly smaller. In a statistically limited comparison the multiplicity in c jets was found to be comparable with that observed for the jets of mixed quark flavour.

Abstract: The production of final states involving one or more energetic photons from e(+)e(-) collisions at high energies is studied using data collected by the ALEPH detector at LEP. The data consist of two samples of 2.9 pb(-1) each, recorded at centre-of-mass energies of 130 GeV and 136 GeV. The data are in agreement with the predictions of the Standard Model. From an analysis of two-photon final states new limits are placed on the parameters of models involving e(+)e(-)gamma gamma contact interactions and excited electrons. The 95% confidence level lower limits on the QED cut-off parameters Lambda(+) and Lambda(-) are found to be 169 and 132 GeV respectively.

Abstract: A search for the radiative decay of excited charged leptons, l*, and for radiative and weak decays of excited electron neutrinos, nu(e)*, is performed, using the 5.8 pb(-1) of data collected by ALEPH at 130-140 GeV. No evidence for a signal is found in single or pair production. Excluded mass limits from pair production are close to 65 GeV/c(2) for all excited lepton species. Limits on the couplings, lambda/m(l*), of excited leptons are derived from single production. For an excited lepton mass of 130GeV/c(2), these limits are 0.04GeV(-1) for mu* and tau*, and 0.0007GeV(-1) for e*.

Abstract: The electroweak mixing angle is determined with high precision from measurements of the mean difference between forward and backward hemisphere charges in hadronic decays of the Z. A data sample of 2.5 million hadronic Z decays recorded over the period 1990 to 1994 in the ALEPH detector at LEP is used. The mean charge separation between event hemispheres containing the original quark and antiquark is measured for b (b) over bar and c (c) over bar events in subsamples selected by their long lifetimes or using fast D*'s. The corresponding average charge separation for light quarks is measured in an inclusive sample from the anticorrelation between charges of opposite hemispheres and agrees with predictions of hadronisation models with a precision of 2%. It is shown that differences between light quark charge separations and the measured average can be determined using hadronisation models, with systematic uncertainties con strained by measurements of inclusive production of kaons, protons and Lambda's. The separations are used to measure the electroweak mixing angle precisely as sin(2) theta(w)(eff) = 0.2322 +/- 0.0008(exp. stat.) +/-0.0007(exp. syst.) +/- 0.0008(sep.). The first two errors are due to purely experimental sources whereas the third stems from uncertainties in the quark charge separations.

Abstract: A search for pair production of new heavy leptons has been performed assuming different scenarios for the mixing of the new particles with Standard Model leptons. No candidate events were found in a data sample corresponding to an integrated luminosity of 5.6 pb(-1) collected by the ALEPH detector at centre-of-mass energies of 130 and 136 GeV. New limits on production cross-sections and on masses of sequential leptons were obtained which significantly extend the mass regions excluded at LEP1. For instance, charged heavy leptons with masses below 63.5 GeV/c(2) are excluded at 95% C.L. for mass differences to the associated neutral lepton of more than 7 GeV/c(2).

Abstract: Hadronic and leptonic cross-sections and forward-backward asymmetries are measured using 5.7 pb(-1) of data taken with the ALEPH detector at LEP at centre-of-mass energies of 130 and 136 GeV. The results agree with Standard Model expectations. The measurement of hadronic cross-sections far away from the Z resonance improves the determination of the interference between photon and Z exchange. Constraints on models with extra Z bosons are presented.

Abstract: The polarization of Λ baryons from Z decays is studied with the Aleph apparatus. Evidence of longitudinal polarization of s quarks from Z decay is observed for the first time. The measured longitudinal Λ polarization is PLΛ = −0.32 ± 0.07 for z = p p beam > 0.3 . This agrees with the prediction of −0.39 ± 0.08 from the standard model and the constituent quark model, where the error is due to uncertainties in the mechanism for Λ production. The observed Λ polarization is diluted with respect to the primary s quark polarization by Λ baryons without a primary s quark. Measurements of the Λ forward-backward asymmetry and of the correlation between back-to-back Λ Λ pairs are used to check this dilution. In addition the transverse Λ polarization is measured. An indication of transverse polarization, more than two standard deviations away from zero, is found along the normal to the plane defined by the thrust axis and the Λ direction.

Abstract: The reaction e(+)e(-) --> HZ is used to search for the Standard Model Higgs boson, The data sample consists of integrated luminosities of 10.9 pb(-1), 1.1 pb(-1), and 9.5 pb(-1) collected by the ALEPH experiment at LEP during 1996, at centre-of-mass energies of 161, 170 and 172 GeV, respectively. No candidate events were found, in agreement with the expected background of 0.84 events from all Standard Model processes. This search results in a 95% C.L. lower limit on the Higgs boson mass of 69.4 GeV/c(2). When combined with earlier ALEPH searches performed at energies at and around the Z peak, this limit increases to 70.7 GeV/c(2). (C) 1997 Elsevier Science B.V.

Abstract: The time dependence of $B^0_d--\bar{B}^0_d$ oscillations is measured by the ALEPH experiment at LEP, using three techniques, two of which are updates of previous measurements. In all cases the charge of the decaying $b$ quark and its decay time are measured in one hemisphere of the event; the quark charge at production is tagged mainly using the opposite hemisphere. The first method uses the charge correlation between a $D^{*-}$ and a lepton in the opposite hemisphere; if no lepton is present, the produced quark charge is determined from the hemisphere charges. In the second method, the decay time is measured using a lepton in one hemisphere and the initial state is inferred from the opposite-hemisphere jet charge. The third method uses a lepton in each hemisphere. The data used were collected from 1991 to 1994. The combined result is $\Delta m_d = 0.436\pm 0.033\, {\rm ps}^{-1}$

Abstract: Studies of QCD in $\mbox{e}^+\mbox{e}^- \rightarrow$ Hadrons at $E_{cm} = $} 130 and 136 GeV The ALEPH Collaboration An analysis of the properties of hadronic final states produced in electron-positron annihilation at centre-of-mass energies of 130 and 136 GeV is presented. The measurements are based on a data sample of 5.7 $\mbox{pb}^{-1}$ collected in November 1995 with the \Aleph detector at LEP. Inclusive charged particle distributions, jet rates and event-shape distributions are measured and the results are compared with the predictions of QCD-based models. From the measured distributions quantities are determined for which the dependence on the centre-of-mass energy can be predicted by QCD, including the mean multiplicity of charged particles, the peak position of the inclusive distribution of $\xi = -\ln x_p$ ($x_p = p / p_{beam}$), and the strong coupling constant $\alpha_s$. The QCD predictions are tested by comparing with corresponding measurements at $E_{cm} = 91.2$ GeV and at lower energies.

Abstract: Searches for charginos and neutralinos produced in e+e− collisions at centre-of-mass energies of 130 and 136 GeV have been performed under the assumptions that R-parity is not conserved, that the dominant R-parity violating coupling involves only leptonic fields, and that the lifetime of the lightest supersymmetric particle can be neglected. In the 5.7 pb−1 data sample collected by ALEPH, no candidate events were found. As a result, chargino and neutralino masses and couplings are constrained and the domains previously excluded at LEP1 are extended.

Abstract: An experimental investigation of the structure of identified quark and gluon jets is presented. Observables related to both the global and internal structure of jets are measured; this allows for tests of QCD over a wide range of transverse momentum scales. The observables include distributions of jet-shape variables, the mean and standard deviation of the subjet multiplicity distribution and the fragmentation function for charged particles. The data are compared with predictions of perturbative QCD as well as QCD-based Monte Carlo models. In certain kinematic regions the measurements are sensitive mainly to perturbatively calculable effects, allowing for a test of QCD. The comparisons are also extended into regions where nonperturbative effects become large, and in this way the transition from hard to soft QCD is investigated. It is found that by including leading and next-to-leading logarithmic contributions in the QCD predictions, the agreement with the data can be extended to lower transverse momentum scales, especially for gluon jets.

Abstract: A search for B0s oscillations is performed using a sample of semileptonic b-hadron decays collected by the ALEPH experiment during 1991-1995. Compared to previous inclusive lepton analyses, the proper time resolution and b-flavour mistag rate are significantly improved. Additional sensitivity to B0s mixing is obtained by identifying subsamples of events having a B0s purity which is higher than the average for the whole data sample. Unbinned maximum likelihood amplitude fits are performed to derive a lower limit of Deltam_s>9.5ps^-1 at 95% CL. Combining with the ALEPH D-s based analyses yields Deltam_s>9.6ps^-1 at 95% CL., 23 pages, 10 figures

Abstract: Searches for scalar top, scalar bottom and degenerate scalar quarks have been performed with data collected with the ALEPH detector at LEP. The data sample consists of 57 pb^-1 taken at sqrt{s} = 181-184 GeV. No evidence for scalar top, scalar bottom or degenerate scalar quarks was found in the channels tilde{t} --> c chi, tilde{t} --> b l snu, tilde{b} --> b chi, and tilde{q} --> q chi. From the channel tilde{t} --> c chi a limit of 74 GeV/c^2 has been set on the scalar top quark mass, independent of the mixing angle. This limit assumes a mass difference between the stop and the chi in the range 10-40 GeV/c^2. From the channel tilde{t} --> b l snu the mixing-angle-independent scalar top limit is 82 GeV/c^2, assuming m_stop - m_snu > 10 GeV/c^2. From the channel tilde{b} --> b chi a limit of 79 GeV/c^2 has been set on the mass of the supersymmetric partner of the left-handed state of the bottom quark. This limit is valid for m_sbottom - m_chi > 10 GeV/c^2. From the channel tilde{q} --> q chi a limit of 87 GeV/c^2 has been set on the mass of supersymmetric partners of light quarks, assuming five degenerate flavours and the production of both ``left-handed'' and ``right-handed'' squarks. This limit is valid for m_squark - m_chi > 5 GeV/c^2., 15 pages, 5 figures, submitted to Physics Letters B

Abstract: From a sample of about 160k Z → τ+τ- candidates collected with the ALEPH detector at LEP between 1991 and 1995, τ lepton decays involving K0S → π+π- are studied. The K0SK0L associated production in τ decays is also investigated. The branching ratios are measured for the inclusive decay B(τ-→K0SX-ν τ) = (9.70±0.58±0.62) × 10-3, where X- can be anything, and for the exclusive decays B(τ-→K̄0π-ν τ) = (8.55±1.17±0.66) × 10-3, B(τ-→K̄0π-π 0ντ) = (2.94±0.73±0.37) × 10-3, B(τ-→K̄0K-ντ) = (1.58±0.42±0.17) × 10-3, B(τ-→K̄0K-π 0ντ) = (1.52±0.76±0.21) × 10-3. The decay τ-→K0SK0 Lπ-ντ is studied for the first time, giving a branching ratio B(τ-→K0SK0 Lπ-ντ) = (1.01±0.23±0.13) × 10-3. The channels τ- → K0SK0Sπ-ν τ , τ- → K0SK0Sπ-π 0ντ , τ- → K0SK0Lπ-π 0ντ , τ- → K̄0π-π0π0ν τ, τ-→K0K-π0π 0ντ and τ-→K0h+h-h -ντ are also investigated. In addition, mass spectra in the K0Sh- and K0Sh-π0 final states are analysed to provide information on the intermediate states produced in the decays.

Abstract: The data collected at centre-of-mass energies ranging from 130 to 172 GeV by ALEPH at LEP, corresponding to an integrated luminosity of 27.5 pb−1, are analysed in a search for pair-produced charged Higgs bosons H±. Three analyses are employed to select the τ + ν τ τ − ν τ , c s τ − ν τ and c s s c final states. No evidence for a signal is found. Mass limits are set as a function of the branching fraction B (τν) for H±→τν. Charged Higgs bosons with masses below 52 GeV/c2 are excluded at 95% C.L. independently of B (τν) , thus significantly improving on existing limits.

Abstract: The triple gauge-boson couplings, αWΦ, αW and αBΦ, have been measured using 34 semileptonically and 54 hadronically decaying W+W- candidate events. The events were selected in the data recorded during 1996 with the ALEPH detector at 172 GeV, corresponding to an integrated luminosity of 10.65 pb-1. The triple gauge-boson couplings have been measured using optimal observables constructed from kinematic information of W+W- events. The results are in agreement with the Standard Model expectation.

Abstract: An analysis based on 124 000 selected τ pairs recorded by the ALEPH detector at LEP provides the vector (V) and axial-vector (A) spectral functions of hadronic τ decays together with their total widths. This allows the evaluation of finite energy chiral sum rules that are weighted integrals over the (V - A) spectral functions. In addition, a precise measurement of αs, along with a determination of non-perturbative contributions at the τ mass scale is performed. The experimentally and theoretically most robust determination of αs(Mτ2) is obtained from the (V + A) fit that yields αs (Mτ2) = 0.334 ±0.022 giving αs (MZ2) = 0.1202 ± 0.0027 after the extrapolation to the mass of the Z boson. The approach of the Operator Product Expansion (OPE) is tested experimentally studying the evolution of the τ hadronic widths to masses smaller than the τ mass.

Abstract: Using approximately 4 million hadronic Z decays recorded with the ALEPH detector from 1991 through 1995, the lifetime of the b baryon is measured with three independent methods. From the impact parameter distribution of candidate leptons in 1063 events with Lambda l(-) combinations, the average b baryon lifetime is measured to be 1.20 +/- 0.08 +/- 0.06 ps. From a sample of 193 fully reconstructed Lambda(c)(+) candidates correlated with a lepton and a sample of 46 Lambda l(+)l(-) combinations the Lambda(b) lifetime is measured to be 1.21+/-0.11 ps. The product branching fractions to these final states are Br(b-->Lambda(b)) . Br(Lambda(b) --> Lambda l(-)(v) over bar X) = 0.326 +/- 0.016 +/- 0.039% for the first sample and Br(b --> Lambda(b)) . Br(Lambda(b) --> Lambda(c)(+)l(-)(v) over bar X) = 0.86 +/- 0.07 +/- 0.14% for the second and third samples combined.
