Abstract: The production rates of D*+-, Ds*+-, D+-, D0 / D0bar, Ds+, and Lambda_c in Z to ccbar decays are measured using the LEP I data sample recorded by the ALEPH detector. The fractional energy spectrum of the D*+- is well described as the sum of three contributions: charm hadronisation, b hadron decays and gluon splitting into a pair of heavy quarks. The probability for a c quark to hadronise into a D*+ is found to be f(c to D*+) = 0.233 +- 0.010 (stat.) +- 0.011 (syst.). The average fraction of the beam energy carried by D*+- mesons in Z to cc events is measured to be < X_E (D*+-) >_cc = 0.4878 +- 0.0046 (stat.) +- 0.0061 (syst.). The D*+- energy and the hemisphere mass imbalance distributions are simultaneously used to measure the fraction of hadronic Z decays in which a gluon splits to a cc pair: n_{gluon to cc} = (3.23 +- 0.48 (stat.) +- 0.53 (syst.) %. The ratio of the Vector/(Vector+Pseudoscalar) production rates in charmed mesons is found to be P_V = 0.595 +- 0.045. The fractional decay width of the Z into cc pairs is determined from the sum of the production rates for various weakly decaying charmed states to be Rc = 0.1738 +- 0.0047 (stat.) +- 0.0116 (syst.)., 25 pages, 13 figures

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: The production rates and the inclusive cross sections of the isovector meson $\pi^0$, the isoscalar mesons $\eta$ and $\eta^\prime(958)$, the strange meson $\mathrm{K^0_S}$ and the $\Lambda$ baryon have been measured as functions of scaled energy in hadronic events two-jet events and each jet of three-jet events from hadronic Z decays and compared to Monte Carlo models. The analysis is based on 3.7~million hadronic events collected with the ALEPH detector at LEP at a centre-of-mass energy of $\sqrt{s}=91.2$~GeV. The JETSET modelling of the gluon fragmentation into isoscalar mesons is found to be in agreement with the experimental results. HERWIG fails to describe the $\mathrm{K^0_S}$ spectra in gluon-enriched jets and the $\Lambda$ spectra in quark jets.

Abstract: Neutral Higgs bosons of the Standard Model and of the MSSM are searched for in the data collected at a centre-of-mass energy of 188.6 GeV by the ALEPH experiment at LEP, with an integrated luminosity of 176 ${\rm pb}^{-1}$. No evidence for a signal is found. A lower limit of 92.9 ${\mathrm{GeV}/c^2}$ at 95% confidence level is set on the mass of the Standard Model Higgs boson, with an expected sensitivity of 95.9 ${\mathrm{GeV}/c^2}$. In the MSSM, for $\tan\beta \ge 0.7$ and for benchmark parameter choices, observed (expected) lower limits of 82.5 (83.1) ${\mathrm{GeV}/c^2}$ and 82.6 (83.2) ${\mathrm{GeV}/c^2}$ are derived for the masses of the neutral Higgs bosons ${\mathrm{h}}$ and ${\mathrm{A}}$, respectively. An update of the general MSSM parameter scan is also presented.

Abstract: The production rates and the inclusive cross sections of the isovector meson pi(0), the isoscalar mesons eta and eta'(958), the strange meson K-S(0) and the Lambda baryon have been measured as functions of scaled energy in hadronic events, two-jet events and each jet of three-jet events from hadronic Z decays and compared to Monte Carlo models. The analysis is based on 3.7 million hadronic events collected with the ALEPH detector at LEP at a centre-of-mass energy of root s = 91.2 GeV. The JETSET modelling of the gluon fragmentation into isoscalar mesons is found to be in agreement with the experimental results. HERWIG fails to describe the K-S(0) spectra in gluon-enriched jets and the A spectra in quark jets.

Abstract: The single top production via flavour changing neutral currents in the reactions ee -> t c/u is searched for in approximately 411 pb-1 of data collected by ALEPH at centre-of-mass energies in the range between 189 and 202 GeV. In total, 58 events are selected in the data to be compared with 50.3 expected from Standard Model backgrounds. No deviation from the Standard Model expectation is observed. A 95\%~CL upper limit of 0.72 pb on the single top production cross section at 202 GeV is derived assuming a top mass of 174 GeV/c^2 and a 100% branching ratio of the top decay into bW. A model dependent limit on the flavour-changing couplings kZ and kg is obtained by combining all centre-of-mass energies.

Abstract: Searches for topologies characteristic of Gauge Mediated SUSY Breaking models (GMSB) are performed by analysing 173.6 pb^-1 of data collected at Ecm = 188.6~GeV with the ALEPH detector.These topologies include acoplanar photons, non-pointing single photon, acoplanar leptons, large impact parameter leptons, detached slepton decay vertices, heavy stable charged sleptons and four leptons plus missing energy final states.No evidence for these new phenomena is observed and limits on production cross sections and sparticle masses are derived. A scan of a minimal GMSB parameter space is performed and model dependent lower limits of about 45 GeV/c^2 on the next-to-lightest supersymmetric particle (NLSP) mass and of about 9 TeV on the mass scale parameter Lambda are derived, independently of the NLSP lifetime.

Abstract: Searches for pair-production of supersymmetric particles under the assumption that R-parity is violated via a single dominant $LL{\bar E}$, $LQ{\bar D}$ or ${\bar U} {\bar D} {\bar D}$ coupling are performed using the data collected by the \ALEPH\ collaboration at centre-of-mass energies of 181--184~$\gev$. The observed candidate events in the data are in agreement with the Standard Model expectations. Upper limits on the production cross-sections and lower limits on the masses of charginos, sleptons, squarks and sneutrinos are de rived.

Abstract: In a recent paper, evidence was presented for a significant, positive correlation between the total transverse momenta of particles on opposite hemispheres of hadronic events. A new, model independent analysis of the data has been made. Two components can be distinguished in the correlation, and quantitative estimates of each are given.

Abstract: Single W production is studied in the data recorded with the ALEPH detector at LEP at centre-of-mass energies between 161 and 183 GeV. The cross section is measured to be sigma_W=0.41+-0.17 (stat) +-0.04 (syst) pb at 183 GeV, consistent with the Standard Model expectation. Limits on non-standard WWgamma couplings are deduced as -1.6 < kg < 1.5 (lg=0) and -1.6 < lg < 1.6 (kg=1) at 95% C.L. A search for effectively invisible decays of the W boson in W pair production is performed, leading to an upper limit on the branching ratio of 1.3% (\Gamma_inv= 27 MeV) at 95% C.L.

Abstract: Data collected at centre-of-mass energies of 181-184 GeV by ALEPH at LEP corresponding to an integrated luminosity of 56.9 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^- nubar_tau, c sbar tau^- nubar_tau/ cbar s tau^+ nu_tau and c sbar s cbar final states. No evidence for a signal is found. Mass limits are set as a function of the branching fraction B(H+ -> tau^+ nu_tau). Under the assumption that the decay modes considered cover the totality of the possible final states, charged Higgs bosons with masses below 59 GeV/c^2 are excluded at 95% C.L. independently of B(H+ -> tau^+ nu_tau)., 14 pages, 5 figures

Abstract: The mass of the W boson is obtained from reconstructed invariant mass distributions in W-pair events. The sample of W pairs is selected from 57 pb−1 collected with the ALEPH detector in 1997 at a centre-of-mass energy of 183 GeV. The invariant mass distributions of reweighted Monte Carlo events are fitted separately to the experimental distributions in the q q q q and all lν q q channels to give the following W masses: m W hadronic =80.461±0.177 (stat.) ±0.045 (syst.) ±0.056 (theory) GeV /c 2 , m W semileptonic =80.326±0.184 (stat.) ±0.040 (syst.) GeV /c 2 , where the theory error represents the possible effects of final state interactions. The combination of these two measurements, including the LEP energy calibration uncertainty, gives m W =80.393±0.128 (stat.) ±0.041 (syst.) ±0.028 (theory) ±0.021 (LEP) GeV /c 2 .

Abstract: The e+e- -> ZZ cross section at sqrt(s)=182.7 and 188.6 GeV has been measured using the ALEPH detector. The analysis covers all of the visible ZZ final states and yields cross section measurements of sigma_ZZ(182.7 GeV) = 0.11 +- (0.16,0.11) (stat.) +- 0.04 (syst.) pb and sigma_ZZ(188.6 GeV) = 0.67 +- 0.13 (stat.) +- 0.04 (syst.) pb consistent with the Standard Model expectations.

Abstract: A search for pair-production of supersymmetric particles under the assumption that R-parity is violated via a dominant LQDbar 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 result is translated into lower limits on the masses of charginos, neutralinos, sleptons, sneutrinos and squarks. For instance, for m_0=500 GeV/c^2 and tan(beta)=sqrt(2) charginos with masses smaller than 81 GeV/c^2 and neutralinos with masses smaller than 29 GeV/c^2 are excluded at the 95% confidence level for any generation structure of the LQDbar coupling.

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- -->lvqq. The branching fraction of hadronic W decays to a final state containing a c quark, R^W_c=Gamma(W-->cX)/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.

Abstract: A measurement of the fraction of hadronic Z decays in which a gluon splits into a $b \bar{b}$ pair, \gbb, is presented using data collected by {\t extsc ALEPH} from 1992 to 1995 at the Z resonance. The selection is based on four-jet events. Events are selected by means of topo logical cuts and a lifetime tag. The result is $g_{b \bar{b}}=(2.77 \pm 0.42 \rm {(stat)} \pm 0.57 \rm{(syst)}) \tim es 10^{-3}$.

Abstract: The flavour changing neutral current decay b -> s gamma has been detected in hadronic Z decays collected by ALEPH at LEP. The signal is isolated in lifetime-tagged b-bbar events by the presence of a hard photon associated with a system of high momentum and high rapidity hadrons. The background processes are normalised from the data themselves.

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: A study of events with photons and missing energy has been performed with the data sample obtained with the ALEPH detector at centre-of-mass energies from 161 to 184 GeV,corresponding to a total integrated luminosity of about 80 pb**-1.The measured distributions are in agreement with Standard Model predictions, leading to constraints on W W gamma gauge coupling parameters Delta(kappa_gamma) and lambda_gamma. The results from the fit to the cross sectionsand to the energy and angular distributions of the photons are: Delta(kappa_gamma) = 0.05 +1.15/-1.10 (stat) +/- 0.25 (syst) lambda_gamma = 0.05 +1.55/-1.45 (stat) +/- 0.30 (syst)

Abstract: A search for B0s oscillations is performed using approximately 4 million Z --> qqbar events collected by the ALEPH experiment during 1991-1995. B0s candidates are partially reconstructed by combining tracks with fully reconstructed Ds- 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 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 B0s lifetime is measured to be tau_s = 1.47 +- 0.14 (stat) +- 0.08 (syst) ps. This analysis selects mainly hadronic B0s decays and is statistically independent of a previous ALEPH analysis selecting B0s --> Ds(*)- l+ nu 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: 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.

Subjects: ALEPH Experiment, LEP, scalar quark search
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 = 181-184 GeV. No evidence for scalar top, scalar bottom or degenerate scalar quarks was found in the channels t~-->cχ, t~-->blν~, b~-->bχ, and q~-->qχ. From the channel t~-->cχ a limit of 74 GeV/c2 has been set on the scalar top quark mass, independent of the mixing angle. This limit assumes a mass difference between the t~ and the χ in the range 10-40 GeV/c2. From the channel t~-->blν~ the mixing-angle-independent scalar top limit is 82 GeV/c2, assuming mt~-mν~ > 10 GeV/c2. From the channel b~-->bχ, a limit of 79 GeV/c2 has been set on the mass of the supersymmetric partner of the left-handed state of the bottom quark. This limit is valid for mb~-mχ > 10 GeV/c2. From the channel q~-->qχ, a limit of 87 GeV/c2 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 mq~-mχ > 5 GeV/c2.

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: Inclusive pi^+/-, K^+/- (p,pbar) production is investigated using data recorded by the ALEPH detector between 1992 and 1994. The momentum spectra and multiplicities are measured separately in Z -->bbar, Z-->ccbar and Z-->uubar,ddbar,ssbar 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)%. From an additional study of proton-lepton correlations in b events the branching ratio Br(b-baryon --> plnuX) = (4.63 +/- 0.72 +/- 0.98)% is obtained. The ratio Br(b-baryon --> plnuX)/ Br(b-baryon --> pX) is found to be 0.080 +/- 0.012 +/- 0.014.

Abstract: The branching fraction for D0 -> K- pi+ is measured with the statistics collected by ALEPH from 1991 to 1994. The method is based on the comparison between the rate for the reconstructed D*+ -> D0 pi+, D0 -> K- pi+ decay chain and the rate for inclusive soft pion production at low transverse momentum with respect to the nearest jet. The result found is B(D0 -> K- pi+) = (3.90 +- 0.09 +- 0.12)%

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 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 132 pb-1 of data collected by ALEPH from 1991 to 1994 have been used to analyze η and ω production in τ decays. The following branching fractions have been measured: B(τ- → ντωh-) = (1.91 ± 0.07 ± 0.06) × 10-2, B(τ- → ντωh-π0) = (4.3 ± 0.6 ± 0.5) × 10-3, B(τ- → ντηK-) = (2.9-1.2+1.3 ± 0.7) × 10-4, B(τ- → ντηh-π0) = (1.8 ± 0.4 ± 0.2) × 10-3 and the 95% C.L. limit B(τ- → ντηπ-) < 6.2 × 10-4 has been obtained. The ωπ- and ηπ-π0 rates and dynamics are found in agreement with the predictions made from e+e- annihilation data with the help of isospin invariance (CVC).

Abstract: For tau leptons produced in e^+e^- -> tau^+ tau^- interactions there are, in addition to the longitudinal spin correlations, two independent transverse spin correlations associated with the transverse (within the production plane) and normal (to the production plane) polarization components. A measurement of the transverse-transverse and transverse-normal tau spin correlations in the decay Z -> tau^+ tau^-, C_{TT} and C_{TN}, is presented based on the aplanarity angle of the decay products of both tau leptons. Using 80 pb^{-1} of data collected by ALEPH on the peak of the Z resonance, the results are C_{TT} = 1.06 +- 0.13 (stat) +- 0.05 (syst), and C_{TN} = 0.08 +- 0.13 (stat) +- 0.04 (syst). These values are in agreement with the Standard Model predictions, C_{TT} = 0.99 and C_{TN} = -0.01.

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: The reaction e+e- -> HZ is used to search for the Standard Model Higgs boson. The data sample consists of integrated luminosities of 10.9pb-1 1.1pb-1 and 9.5pb-1 collected by the ALEPH experiment at LEP during 1996, at centre-of-mass energies of 161, 170 and 172GeV, 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 69.4GeV. When combined with earlier ALEPH searches performed at energies at and around the Z peak, this limit increases to 70.7GeV

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: Two samples of exclusive semileptonic decays, 579 B0->D*+l-nu events and 261 B0->D+l-nu 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(w) at zero recoil of the D(*)+ meson and the CKM matrix element |Vcb| are measured to be FD*+(1)|Vcb| = (31.9 +/- 1.8(stat) +/- 1.9(syst) ) Mail afs archive asis auth bin boot categ cern collab comments core date dev drdspool etc export external_repno filename ftp home kadb lib lost+found mail mbox mnt nfs nsr old_archive old_drdspool old_pub opt pages pcfs pub publi publitype reconfigure ref repno sbin share sys tit tmp usr var vmunix 10**-3, FD+(1)|Vcb| = (27.8 +/- 6.8(stat) +/- 6.5(syst) ) Mail afs archive asis auth bin boot categ cern collab comments core date dev drdspool etc export external_repno filename ftp home kadb lib lost+found mail mbox mnt nfs nsr old_archive old_drdspool old_pub opt pages pcfs pub publi publitype reconfigure ref repno sbin share sys tit tmp usr var vmunix 10**-3.

Abstract: About three million hadronic decays of the Z collected by ALEPH in the years 1991-1994 are used to search for anomalous CP violation beyond the Standard Model in the decay Z -> b \bar{b} g. The study is performed by analyzing angular correlations between the two quarks and the gluon in three-jet events and by measuring the differential two-jet rate. No signal of CP violation is found. For the combinations of anomalous CP violating couplings, ${\hat{h}}_b = {\hat{h}}_{Ab}g_{Vb}-{\hat{h}}_{Vb}g_{Ab}$ and $h~{\ast}_b = \sqrt{\hat{h}_{Vb}~{2}+\hat{h}_{Ab}~{2}}$, limits of \hat{h}_b < 0.59$ and $h~{\ast}_{b} < 3.02$ are given at 95\% CL.

Abstract: A lower limit on the oscillation frequency of the BsBsbar system is obtained from approximately four million hadronic Z decays accumulated using the ALEPH detector at LEP from 1991 to 1995. Leptons are combined with opposite sign Ds- candidates reconstructed in seven different decay modes as evidence of semileptonic Bs decays. Criteria designed to ensure precise proper time reconstruction select 277 Ds-,l+ combinations. The initial state of these Bs candidates is determined using an algorithm optimized to efficiently utilise the tagging information available for each event. The limit at 95\% confidence level on the BsBsbar oscillation frequency is delta_m_s > 6.6 ps^-1. The same data is used to update the measurement of the Bs lifetime, tau_s = 1.54 +0.14 (stat) +0.04 (syst) ps. -0.13 -0.04

Abstract: The lifetimes of the \b0 \ and \bp\ mesons have been measured with the \aleph\ detector at LEP, using approximately 3 million hadronic Z decays collected in the period 1991--1994. In the first of three methods, semileptonic decays of \b0 \ and \bp\ mesons were partially reconstructed by identifying events containing a lepton with an associated \ds\ or \d0 \ meson. The second method used fully reconstructed \bz\ and \bp\ mesons. The third method, used to measure the \bz\ lifetime, employed a partial reconstruction technique to identify \bz\to D^{*+}\pi^- X decays. The combined results are \begin{eqnarray*} \t0 & = & 1.55\pm 0.06\pm 0.03 \mathrm{\ ps}, \\ \tp & = & 1.58\pm 0.09\pm 0.03 \mathrm{\ ps}, \\ \trat & = & 1.03\pm 0.08\pm 0.02.

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.
