Abstract: A search for Bs0 oscillations is performed using a sample of semileptonic b-hadron decays collected by the ALEPH experiment during 1991-95. Compared to previous inclusive lepton analyses, the proper time resolution and b-flavour mistag rate are significantly improved. Additional sensitivity to Bs0 mixing is obtained by identifying subsamples of events having a Bs0 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 Δms > 9.5 ps-1 at the 95% confidence limit (95% CL). Combining with the ALEPH Ds--based analyses yields Δms > 9.6 ps-1 at 95% CL.

Abstract: The inclusive charm production rate in W decays is measured from a study of the properties of final state particles. The sample of W pairs is selected from 67.7 pb(-1) collected by ALEPH in 1996 and 1997 at centre-of-mass energies near 172 and 183 GeV in the channels W+W- --> 4q and W+W- --> l . The branching fraction of hadronic W decays to a final state containing a c quark, R-c(W) = Gamma(W --> hadrons), is measured to be 0.51 +/- 0.05(stat) +/- 0.03(syst). This allows a direct determination of the CKM matrix element \V-cs\ = 1.00 +/- 0.11(stat) +/- 0.07(syst). (C) 1999 Published by Elsevier Science B.V. All rights reserved.

Abstract: During 1997 the ALEPH experiment at LEP gathered 57 pb(-1) of data at centre-of-mass energies near 183 GeV. These data are used to look for possible signals from the production of the Standard Model Higgs boson in the reaction e(+)e(-) --> HZ. No evidence of a signal is found in the data; seven events are selected, in agreement with the expectation of 7.2 events from background processes. This observation results in an improved lower limit on the mass of the Higgs boson: m(H) greater-than 87.9 GeV/c(2) at 95% confidence level. (C) 1999 Elsevier Science B.V. All rights reserved.

Abstract: The production of charmed mesons {Mathematical expression}, D±, and D*± is studied in a sample of 478,000 hadronic Z decays. The production rates are measured to be {Mathematical expression} where the errors from this analysis are separated from those coming from the D branching ratios (BR). The D*± momentum distribution is extracted separately for {Mathematical expression} and {Mathematical expression} events with the help of event shape variables. It is consistent with the prediction of the JETSET Monte Carlo program after adjustment of the charm fragmentation function. Constraining the shape of the {Mathematical expression} contribution, the average fraction of the beam energy taken by a D* meson produced in the fragmentation of a charm quark is extracted by a parametric fit to be c=0.495±0.011±0.007. Evidence for D**0 (D1(2420)0 and/or D2 *(2460)0) production is found in the {Mathematical expression} channel, accounting for a fraction (18±5±2)% of all D*± production. The relative production of vector and pseudoscalar mesons is dicussed, together with the possible effects of D** production. The c-quark forward-backward Z-pole asymmetry is detrmined from that of high momentum D*± to be AFB 0,c=(7.7±4.4)%.

Abstract: Semileptonic decays of heavy quarks yield prompt leptons which can be used to identify events resulting from the decays of the Z into cc and bb pairs. The procedures adopted to obtain clean samples of inclusive leptons with the ALEPH detector are described. Electron identification makes use of ionization measurements in the tracking system of ALEPH and the shape of showers in the electromagnetic calorimeter. Muons are identified using the tracking capabilities of the hadron calorimeter, together with the muon chamber information. Distinguishing the sources of prompt lepton production requires the determination of the lepton's transverse momentum with respect to the parent hadron's flight direction. As the latter is not directly measurable, the results of an algorithm are presented which uses the information produced by the ALEPH detector to achieve the most effective axis from which the transverse momentum should be measured.

Abstract: Using 18.8 pb-1 of data collected in 1990 and 1991, ALEPH has measured the tau polarisation in the decay modes tau-->enunuBAR, tau-->mununuBAR, tau-->rhonu tau-->a1nu, using both the individual tau decay kinematics and the event acollinearity. The measurement of the tau polarisation as a function of the production polar angle yields the two parameters A(tau) and A(e), where A(l) = 2g(V)l g(A)l/[(g(V)l)2 + (g(A)l)2]. The results A(tau) = 0.143 +/- 0.023 and A(e) = 0. 120 +/- 0.026 are consistent with the hypothesis of electron-tau universality. Assuming universality yields a measurement of the effective weak mixing angle sin 2theta(W)eff = 0.2332 +/- 0.0022.

Abstract: The production of isolated photons in hadronic Z decays is measured with the ALEPH detector at LEP using a sample of 450 000 hadronic events. The corrected rate is given for several values of the minimum invariant mass squared cut between the photon and the jets. This measurement of final state radiation from the quarks is compared with the predictions of parton shower models JETSET, ARIADNE and HERWIG as well as with the predictions of QCD matrix element calculations.

Abstract: A measurement of the average lifetime of b hadrons has been performed with dipole method on a sample of 260 000 hadronic Z decays recorded with the ALEPH detector during 1991. The dipole is the distance between the vertices built in the opposite hemispheres. The mean dipole is extracted from all the events without attempting b enrichment. Comparing the average of the data dipole distribution with a Monte Carlo calibration curve obtained with different b lifetimes, an average b hadron lifetime of 1.51±0.08 ps is extracted.

Abstract: During 1989 and 1990 over 180 000 hadronic and leptonic events, corresponding to 8 pb-1 of luminosity, were collected by the ALEPH detector in a scan of the Z peak at the e+e- collider LEP. This letter reports the results of a search in these data for particles with unexpected mass and charge by measurement of the ionization energy loss of charged tracks in the ALEPH TPC central tracking detector. The mass limits for the pair production of fractionally charged particles and of heavy, long lived charged particles are extended to 43 GeV/c2 at 90% confidence level. If single production of a heavy particle is considered, the mass limit is extended to more than 70 GeV/c2.

Abstract: A data sample corresponding to 1.23 million hadronic Z decays collected by the ALEPH detector at LEP has been searched for signals of the production of a non-minimal CP-even Higgs boson h in the reaction e+e- → hZ*. The h decay modes considered were: those of the minimal standard model Higgs boson, with modified branching ratios; decays into a pair of CP-odd Higgs bosons A; and decays into invisible final states. Only one event was found, a very acoplanar e+e- pair which could originate from the standard model background process e+e- → e+e-v v ̄. Upper limits for the cross-section of the reaction e+e- → hZ* have been derived as a function of mh, the mass of the Higgs boson h. In the case of invisible decays, the 95% CL lower limit on mh is 65 GeV/c2 for a production cross-section equal to that of a minimal standard model Higgs boson. When combined with previous ALEPH results on the reaction e+e- → hA, these cross-section upper limits exclude a domain in the (mh mA) plane of the MSSM such that if invisible h and A decays can be neglected, 95% CL lower limits of 44 and 21 GeV/c2 result for mh and mA, respectively, independent of the other parameters of the model.

Abstract: Using 106 000 hadronic events obtained with the ALEPH detector at LEP at energies close to the Z resonance peak, the strong coupling constant αs is measured by an analysis of energy-energy correlations (EEC) and the global event shape variables thrust, C-parameter and oblateness. It is shown that the theoretical uncertainties can be significantly reduced if the final state particles are first combined in clusters using a minimum scaled invariant mass cut, Ycut, before these variables are computed. The combined result from all shape variables of pre-clustered events is αs(MZ2 = 0.117±0.005 for a renormalization scale μ= 1 2 M Z . For μ values between MZ and the b-quark mass, the result changes by −0.009+0.006.

Abstract: Searches for supersymmetric particles in channels with one or more photons and missing energy have been performed with data collected by the ALEPH detector at LEP. The data consist of 11.1 pb(-1) at root s = 161 GeV, 1.1 pb(-1) at 170 GeV and 9.5 pb(-1) at 172 GeV. The e(+) e(-) --> nugamma(gamma) cross section is 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. These limits are compared to two different SUSY models and used to set limits on the neutralino mass. A limit of 71 GeV/c(2) at 95% C.L, is set on the mass of the lightest neutralino (tau(chi 1)(o) less than or equal to 3 ns) for the gauge-mediated supersymmetry breaking and LNZ models.

Abstract: The triple gauge-boson couplings, alpha(W phi), alpha(W) and alpha(B psi), 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. (C) 1998 Elsevier Science B.V.

Abstract: During 1997 the ALEPH experiment at LEP gathered 57 pb(-1) of data at centre-of-mass energies near 183 GeV. These data are used to look for possible signals from the production of the Standard Model Higgs boson in the reaction e(+)e(-) --> HZ. No evidence of a signal is found in the data; seven events are selected, in agreement with the expectation of 7.2 events from background processes. This observation results in an improved lower limit on the mass of the Higgs boson: m(H) > 87.9 GeV/c(2) at 95% confidence level. (C) 1998 Elsevier Science B.V. All rights reserved.

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: An analysis based on 124000 selected tau pairs recorded by the ALEPH detector at LEP provides the vector (V) and axial-vector (A) spectral functions of hadronic tau 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 alpha(s) along with a determination of nonperturbative contributions at the tau mass scale is performed. The experimentally and theoretically most robust determination of alpha(s)(M-tau(2)) is obtained from the (V + A) fit that yields alpha(s)(M-tau(2)) = 0.334 +/- 0.022 giving alpha(s)(M-Z(2)) = 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 tau hadronic widths to masses smaller than the tau mass.

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.

Abstract: A bound on the tau neutrino mass is established using the data collected from 1991 to 1995 at root s similar or equal to m(Z) with the ALEPH detector. Two separate limits are derived by fitting the distribution of visible energy vs invariant mass in tau(-) --> 2 pi(-)pi(+)nu(tau) --> 3 pi(-)2 pi(+)(pi(0))nu(tau) decays. The two results are combined to obtain a 95% confidence level upper limit of 18.2MeV/c(2) on the mass of the tau neutrino.

Abstract: A search for B0s oscillations is performed using approximately 4 million Z → qq̄ events collected by the ALEPH experiment during 1991-1995. B0s candidates are partially reconstructed by combining tracks with fully reconstructed D-s candidates. The B0s production flavour is estimated from the sign of the opposite hemisphere charge, a fragmentation kaon in the same hemisphere, or a lepton in the opposite hemisphere. From a total sample of 1620 candidates, with a B0s purity estimated to be 22%, all values of Δms below 3.9 ps-1 and between 6.5 and 8.8 ps-1 are excluded at 95% CL. From the same sample, the B0s lifetime is measured to be τs = 1.47 ± 0.14(stat) ± 0.08(syst) ps. This analysis selects mainly hadronic B0s decays and is statiscally independent of a previous ALEPH analysis selecting B0s → D(*)-s ℓ+ v candidates. Combining these two analyses yields Δms > 7.9 ps-1 at 95% CL and τs = 1.51 ± 0.11 ps.

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 tau(+)nu(tau)tau(-), (-) and c (s) over bar s (c) over bar final states. No evidence for a signal is found. Mass limits are set as a function of the branching fraction B(tau nu) for H(+/-)-->tau nu. Charged Higgs bosons with masses below 52 GeV/c(2) are excluded at 95% C.L. independently of B(tau nu) thus significantly improving on existing limits. (C) 1998 Published by Elsevier Science B.V.

Abstract: Inclusive pi(+/-), K+/- and (p,(p)over-bar) production is investigated using data recorded by the ALEPH detector between 1992 and 1994. The momentum spectra and multiplicities are measured separately in Z --> b(b)over-bar, Z --> c(c)over-bar and Z --> u(u)over-bar, d(d)over-bar; s(s)over-bar decays. The number of protons found in b-hadron decays is used to estimate the fraction of b-baryons in b events to be (10.2 +/- 0.7 +/- 2.7)% assuming BR(b-baryon --> pX) = (58 +/- 6)%. From an additional study of proton-lepton correlations in b events, the branching ratio BR(b-baryon --> pl(v)over-bar-X) = (4.63 +/- 0.72 +/- 0.98)% is obtained. The ratio BR(b-baryon --> pl(nu)over-bar-X)/BR(b-baryon --> pX) is found to be 0.080 +/- 0.012 +/- 0.014.

Abstract: A search for B-s(o) oscillations is performed using approximately 4 million Z --> q (q) over bar events collected by the ALEPH experiment during 1991-1995. B-s(o) candidates are partially reconstructed by combining tracks with fully reconstructed D-s(-) candidates. The B-s(o) production flavour is estimated from the sign of the opposite hemisphere charge, a fragmentation kaon in the same hemisphere, or a lepton in the opposite hemisphere. From a total sample of 1620 candidates, with a B-s(o) purity estimated to be 22%, all values of Delta m(s) below 3.9 ps(-1) and between 6.5 and 8.8 ps(-1) are excluded at 95% CL. From the same sample, the B-s(o) lifetime is measured to be tau(s) = 1.47 +/- 0.14(stat) +/- 0.08(syst) ps. This analysis selects mainly hadronic B-s(o) decays and is statistically independent of a previous ALEPH analysis selecting B-s(o) --> D-s((*)-) rho(+)upsilon candidates. Combining these two analyses yields Delta m(s) > 7.9 ps(-1) at 95% CL and tau(s) = 1.51 +/- 0.11 ps.

Abstract: The four jet topology is analysed in the ALEPH data taken between November 1995 and October 1997, at centre-of-mass energies ranging from 130 to 184 GeV, While an unexpected accumulation of events with a dijet mass sum around 105 GeV/c(2) had been observed during the first run in 1995 at 130/136 GeV, corresponding to an integrated luminosity of 5.7 pb(-1), no significant differences between data and standard model prediction is seen, either in the high energy runs (81.1 pb(-1) taken at centre-of-mass energies from 161 to 184 GeV) or in the 7.1 pb(-1) recorded during a new short fun at 130/136 GeV in 1997, We have found no other explanation for the earlier reported "four jet anomaly" than a statistical fluctuation.

Abstract: A search for pair-production of supersymmetric particles under the assumption that R-parity is violated via a dominant LL (E) over bar coupling has been performed using the data collected by ALEPH at centre-of-mass energies of 130-172 GeV. The observed candidate events in the data are in agreement with the Standard Model expectation. This is translated into lower limits on the mass of charginos, neutralinos, sleptons, sneutrinos and squarks. For instance, charginos with masses less than 73 GeV/c(2) and neutralinos with masses less than 23 GeV/c(2) are excluded at 95% confidence level for any generation structure of the LL (E) over bar coupling, and for neutralino, slepton or sneutrino LSPs.

Abstract: A search for doubly-charmed B decays with both charmed mesons reconstructed is performed, using about 3.8 million hadronic Z decays recorded with the ALEPH detector at LEP. A clear signal is observed in the channels ${\mathrm B\rightarrow D_s \bar D}(X)$ and ${\mathrm B\rightarrow D \bar D}(X)$ (where D can be either a D$^0$, a D$^+$ or a D$^{*+}$), providing the first direct evidence for doubly-charmed B decays involving no ${\mathrm D_s}$ production. Evidence for associated ${\mathrm K^0_S}$ and ${\mathrm K^{\pm}}$ production in the decays ${\mathrm B\rightarrow D \bar D}(X)$ is also presented and some candidates for completely reconstructed decays ${\mathrm B\rightarrow D_s \bar D}(n\pi)$, ${\mathrm B\rightarrow D \bar D K^0_S}$ and ${\mathrm B\rightarrow D \bar D K^\pm}$ are observed. Furthermore, candidates for the two-body Cabibbo suppressed decays ${\mathrm B^0\rightarrow D^{*-}D^{*+}}$ and ${\mathrm B^-\rightarrow D^{(*)0}D^{(*)-}}$ are also observed. Measurements of the corresponding branching fractions are extracted.

Abstract: An improved measurement of the average lifetime of b hadrons has been performed with the ALEPH detector. From a sample of 260 000 hadronic Z0 decays, recorded during the 1991 LEP run with the silicon vertex detector fully operational, a fit to the impact parameter distribution of lepton tracks coming from semileptonic decays yields an average b hadron lifetime of 1.49 ± 0.03 ± 0.06 ps.

Abstract: A sample of 4148 four-jet events observed in the ALEPH-detector at LEP in 1989 and 1990 is used to test the underlying gauge group of strong interactions. A fit to the ratios of the "colour factors" C(F), N(C) and T(F), which determine the differential cross sections, yields N(C)/C(F) = 2.24 +/- 0.32stat +/- 0.24syst and T(F)/C(F) = 0.58 +/- 0.17stat +/- 0.23syst. This is in agreement with the values expected from QCD: N(C)/C(F) = 2.25 and T(F)/C(F) = 0.375. The non-zero value of N(C)/C(F) constitutes direct evidence for the existence of the triple-gluon coupling and excludes any abelian gauge theory by more than five standard deviations.

Abstract: wo samples of exclusive semileptonic decays, 579 B̄0 → D*+ℓ-v̄ℓ events and 261 B̄0 → D+ℓ-v̄ℓ 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 factors ℱD+(1) and ℱD*+ (1) is measured to be ℱD+(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(B̄0 → D*+ℓ-v̄ℓ) = (5.53 ± 0.26stat ± 0.52syst)%,Br(B̄0 → D+ℓ-v̄ℓ) = (2.35 ± 0.20stat ± 0.445syst)%.

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: The time dependence of B-d(-)(B) over bar(d)(-0) 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)=0.446+/-0.032 ps(-1).

Abstract: The time dependence of Bd0-B̄d0 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 Δmd = 0.446 ± 0.032 ps-1.

Abstract: The 132 pb(-1) of data collected by ALEPH from 1991 to 1994 have been used to analyze eta and omega production in 7 decays. The following branching fractions have been measured: B(tau(-) --> nu(tau)omega h(-)) = (1.91 +/- 0.07 +/- 0.06) x 10(-2), B(tau(-) --> nu(tau)omega h(-)pi(0)) = (4.3 +/- 0.6 +/- 0.5) x 10(-3), B(tau(-) --> nu(tau)eta K-) = (2.9(-1.2)(+1.3) +/- 0.7) x 10(-4), B(tau(-) --> nu(tau)eta(h)(-)pi(0)) = (1.8 +/- 0.4 +/- 0.2) x 10(-3) and the 95% C.L. limit B(tau(-) --> nu(tau)eta pi(-)) < 6.2 x 10(-4) has been obtained. The omega pi(-) and eta pi(-)pi(0) rates and dynamics are found in agreement with the predictions made from e(+)e(-) annihilation data with the help of isospin invariance (CVC).

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: 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 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 = - 1nx(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: A new method is presented for the measurement of the mean tau lepton lifetime using events in which tau's are pair-produced and both tau's decay to hadrons and nu(tau). Based on the correlation between the two tau's produced at a symmetric e(+)e(-) collider, the 3DIP method relies on the three-dimensional information from a double-sided vertex detector and on kinematic constraints for the precise measurement of the tau decay angles. Using the data collected from 1992 to 1994 with the ALEPH detector at LEP, a tau lifetime of 288.0 +/- 3.1 +/- 1.3 fs is obtained from the sample in which both tau's decay to one charged track, and 292.8 +/- 5.6 +/- 3.0 fs from the sample in which one tau decays to one prong and the other to three prongs. The results show small statistical correlations with those derived from other methods. When combined with the previously published ALEPH measurements, the resulting tau lifetime is 291.2 +/- 2.0 +/- 1.2 fs.

Abstract: Two samples of exclusive semileptonic decays, 579 (B) over bar(0) --> D*(+)l(-)(v) over bar(l) events and 261 (B) over bar(0) --> D(+)l(-)(v) over bar(l) 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(omega) at zero recoil of the D-(*+) meson and the CKM matrix element \V-cb\ are measured to be FD*+(1)\V-cb\ = (31.9 +/- 1.8(stat) +/- 1.9(syst)) x 10(-3), FD+(1)\(V-cb\ = (27.8 +/- 6.8(stat) +/- 6.5(syst)) x 10(-3). The ratio of the form factors FD+(1) and FD*+(1) is measured to be FD+(1)/FD*+(1) = 0.87 +/- 0.22(stat) +/- 0.21(syst). A value of \V-cb\ 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 \V-cb\ = (34.4 +/- 1.6(stat)+/- 2.3(syst) +/- 1.4(th)) x 10(-3). The branching fractions are measured from the two integrated spectra to be Br((B) over bar(0) --> D(*+)l(-)(v) over bar(l)) = (5.53 +/- 0.26(stat) +/- 0.52(syst))%, Br((B) over bar(0) --> D(+)l(-)(v) over bar(l)) = (2.35 +/- 0.20(stat) +/- 0.44(syst))%.

Abstract: An analysis of the properties of hadronic final states produced in electron-positron annihilation at centre-of-mass energies of 130 and 136GeV is presented. The measurements are based on a data sample of 5.7 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 ξ = -In xp (xp = p/pbeam), and the strong coupling constant αs. The QCD predictions are tested by comparing with corresponding measurements at Ecm = 91.2GeV and at lower energies.

Abstract: Inclusive beauty-quark production in two-photon collisions has been measured at LEP using an integrated luminosity of 698 pb-1 collected by the ALEPH detector with sqrt(s) between 130 and 209 GeV. The b quarks were identified using lifetime information. The cross section is found to be sigma(e+ e- --> e+ e- b \bar{b} X) = (5.4 +/- 0.8 (stat) +/- 0.8 (syst)) pb which is consistent with Next-to-Leading Order QCD., 15 pages, 8 figures.
