Abstract: A study of the polarization of $\Lambda$ hyperons produced in inelastic pN reactions induced by the 450 GeV proton beam from the CERN SPS has been performed with the NA48 detector. The $\Lambda$ hyperons were detected at a fixed angle of 4.2 mrad in the momentum range from 50 GeV/c to 200 GeV/c. The polarization changes from $-0.053 \pm 0.034$ to $-0.298 \pm 0.074$ for a transverse momentum range of the $\Lambda$ between 0.28 GeV/c and 0.86 GeV/c. The $\overline{\Lambda}$ polarization is consistent with zero.

Abstract: The eects of space charge due to slowly drifting ions can be relevant for detectors operated at high intensity, or for relatively low values of the bias voltage. Accurate measurements have been obtained with the liquid krypton calorimeter of the NA48 experiment, from data collected in 1997. The build-up of space charge takes place during the rst part of the beam extraction burst, and causes a dependence of the response on the transverse coordinate of the axis of electromagnetic showers, and a small reduction of average amplitude. The eects are well reproduced by a computation, where the only free parameter is the value of the ion mobility. The model can be applied a wide range of operating conditions, and generalized to detectors with dierent geometry and active medium. Ionization detectors are usually not aected by ions, because the induced signal is dominated by the fast drifting electrons, and the total amount of ion charge accumulated in the detector cell is typically much smaller than the charge stored on the electrodes. However, space charge can produce observable eects in case of large particle intensities, or for relatively low values of the bias voltage. The liquid krypton calorimeter for the NA48 experiment at CERN was operated in 1997 with the bias voltage set at 1.5 kV over a gap of 1 cm, half of the value used in the following years. In this condition, small but precisely measurable eects of space charge have been observed. In the following sections, after a brief discussion of the design and performance of the NA48 calorimeter, a model of space charge eects in parallel plate detectors is described, and compared to experimental observations. A characteristic, dimensionless parameter is identied, and predictions over wide ranges of operating conditions, cell geometry, and dierent active media are

Abstract: A sample of 2.2 million hadronic Z decays, selected from the data recorded by the Delphi detector at LEP during 1994-1995 was used for an improved measurement of inclusive distributions of pi+, K+ and p and their antiparticles in gluon and quark jets. The production spectra of the individual identified particles were found to be softer in gluon jets compared to quark jets, with a higher multiplicity in gluon jets as observed for inclusive charged particles. A significant proton enhancement in gluon jets is observed indicating that baryon production proceeds directly from colour objects. The maxima, xi^*, of the xi-distributions for kaons in gluon and quark jets are observed to be different., 24 pages, 12 figures

Abstract: The cross-section for the process $e^+e^-\rightarrow W^+W^-$ has been measured with the data sample collected by DELPHI at an average centre-of-mass energy of 182.65 GeV and corresponding to an integrated luminosity of 53 pb$^{-1}$. Based on the 770 events selected as $WW$ candidates, the cross-section for the doubly resonant process $ \sigma (e^+e^-\rightarrow W^+W^-) = 15.86~{\pm 0.69}~\mbox{(stat)} ~\pm 0.26~\mbox{(syst)~pb} $ has been measured and found to be in good agreement with the Standard Model expectation. The branching fractions of the $W$ decay were also measured. From these a value of the CKM mixing matrix element $ |V_{cs}| = 0.985 \pm 0.073~\mbox{(stat)} \pm 0.025 ~\mbox{(syst)}$ was derived. Our previously published $WW$ cross-section measurements and the derived measurement of $m_W$ have been revised and updated with the present cross-section measurement to yield $ m_W = 80.49 \pm 0.43 \mbox{(stat)} \pm 0.09 (\mathrm{syst}) \pm 0.03 (\mathrm{LEP})~{\mathrm GeV}/{\it c}^2$.

Abstract: Infrared and collinear safe event shape distributions and their mean values are determined using the data taken at five different centre of mass energies above MZ with the DELPHI detector at LEP. From the event shapes, the strong coupling alphaS is extracted in Î ̧(Î±S2), NLLA and a combined scheme using hadronisation corrections evaluated with fragmentation model generators as well as using an analytical power ansatz. Comparing these measurements to those obtained at MZ, the energy dependence (running) of alphaS is accessible. The logarithmic energy slope of the inverse strong coupling is measured to be d Î±S-1/d log (Ecm) = 1.39 + 0.34(stat) + 0.17(syst), in good agreement with the QCD expectation of 1.27.

Abstract: Data collected at the Z resonance using the DELPHI detector at LEP are used to determine the charged hadron multiplicity in gluon and quark jets as a function of a transverse momentum-like scale. The colour factor ratio, CA/CF, is directly observed in the increase of multiplicities with that scale. The smaller than expected multiplicity ratio in gluon to quark jets is understood by differences in the hadronization of the leading quark or gluon. From the dependence of the charged hadron multiplicity on the opening angle in symmetric three-jet events the colour factor ratio is measured to be: CA/CF= 2.246 ± 0.062(stat.) ± 0.080 (syst.) ± 0.095 (theo.) © 1999 Elsevier Science B.V.

Abstract: A new precise measurement of |Vcb| and of the branching ratio BR(B̄0 → D*+ℓ-v̄ℓ) has been performed using a sample of about 5000 semileptonic decays B̄0 → D*+ℓ-v̄ℓ, selected by the DELPHI detector at LEP I by tagging the soft pion from D*+ → D0π+. The results are: Vcb = (39.0 ± 1.5 (stat.)-2.6+2.5 (syst. exp.) ± 1.3 (syst. th.)) × 10-3, BR(B̄0 → D*+ℓ-v̄ℓ) = (4.70 ± 0.13 (stat.)-0.31+0.36 (syst. exp.))%. The analytic dependencies of the differential cross-section and of the Isgur-Wise form factor as functions of the variable w = vB0 · vD* have also been obtained by unfolding the experimental resolution. © 2001 Published by Elsevier Science B.V.

Abstract: Searches for supersymmetric partners of top and bottom quarks are presented using data taken by the DELPHI experiment at LEP in 1997 and 1998. No deviations from standard model expectations are observed in these data sets, which are taken at centre-of-mass energies of 183 GeV and 189 GeV and correspond to integrated luminosities of 54 pb(-1) and 158 pb(-1). These results are used in combination with those obtained by DELPHI at lower centre-of-mass energies to exclude regions in the squark-neutralino mass plane at 95% confidence level.

Abstract: The DELPHI detector at LEP has collected 54 pb(-1) of data at a centre-of-mass energy around 183 GeV during 1997, 158 pb(-1) around 189 GeV during 1998, and 187 pb(-1) between 192 and 200 GeV during 1999. These data were used to measure the average charged particle multiplicity in e(+)e(-)->b (b) over bar events: (n)(b (b) over bar), and the difference delta(hl) between (n)(b (b) over bar) and the multiplicity, (n)(l (l) over bar), in generic light quark (u,d,s) events: delta(hl)(183 GeV) = 4.55 +/- 1.31(stat) +/- 0.73(syst), delta(hl)(189 GeV) = 4.43 +/- 0.85(stat) +/- 0.61(syst), delta(hl)(200 GeV) = 3.39 +/- 0.89(stat) +/- 1.01 (syst). This result is consistent with QCD predictions, while it is inconsistent with calculations assuming that the multiplicity accompanying the decay of a heavy quark is independent of the: mass of the quark itself.

Abstract: The cross-section for the process e+e- -> W+W- has been measured with the data sample collected by DELPHI at an average centre-of-mass energy of 189 GeV and corresponding to an integrated luminosity of 155 pb^{-1}. Based on the 2392 events selected as WW candidates, the cross-section for the doubly resonant process e+e- -> W+W- has been measured to be 15.83 +- 0.38 (stat) +- 0.20 (syst) pb. The branching fractions of the W decay were also measured and found to be in good agreement with the Standard Model expectation. From these a value of the CKM mixing matrix element |V_{cs}| = 1.001 +- 0.040 (stat) +- 0.020 (syst) was derived., 16 pages, 4 figures

Abstract: The data collected by DELPHI in 1998 at the centre-of-mass energy of 189 GeV have been used to update the search for charginos nearly mass-degenerate with the lightest supersymmetric particle, which is assumed to be the lightest neutralino. Mass differences below \Delta M = 3 GeV/c^2 are considered. No excess of events with respect to the Standard Model expectation has been observed, and exclusions in the plane of \Delta M versus chargino mass are given. The new \Delta M independent lower limit on the mass of the chargino is 62.4 GeV/c^2 in the higgsino scenario (which includes the gaugino mass unification scenario), if all sfermions are heavier than the lightest chargino. In the approximation of large sfermion masses the limit is 59.8 GeV/c^2, independently of the field content., Comment: 14 pages, 5 figures

Abstract: Measurements of the trilinear gauge boson couplings WW gamma and WWZ are; presented using the data taken by DELPHI in 1998 at a centre-of-mass; energy of 189 GeV and combined with DELPHI data at 183 GeV. Values are; determined for Deltag(1)(Z) and Delta kappa (gamma), the differences of; the WWZ charge coupling and of the WWgamma dipole coupling from their; Standard Model values, and for hy, the WW gamma quadrupole coupling. A; measurement of the magnetic dipole and electric quadrupole moment of the; W is extracted from the results for Delta kappa (gamma) and lambda; (gamma). The study uses data from the final states jjl nu, jjjj, lX, jjX; and gammaX where j represents a quark jet, l an identified lepton and X; missing four-momentum. The observations are consistent with the; predictions of the Standard Model. (C) 2001 Published by Elsevier; Science B.V. Searches for neutral Higgs bosons in the Standard Model and the MSSM have been performed using data collected by the DELPHI experiment at a centre-of-mass energy of 188.7 GeV, corresponding to an integrated luminosity of 158 pb(-1). These analyses are used, in combination with our results from lower energies, to set new 95% confidence level lower mass bounds on the Standard Model Higgs boson (94.6 GeV/c(2)) and on the lightest neutral scalar (82.6 GeV/c(2)) and neutral pseudoscalar (84.1 GeV/c(2)) Higgs bosons in a representative scan of the MSSM parameters. The results are also interpreted in the framework of a general two-Higgs doublet model.

Abstract: We report on the final electroweak measurements performed with data taken at the Z resonance by the experiments operating at the electron-positron colliders SLC and LEP. The data consist of 17 million Z decays accumulated by the ALEPH, DELPHI, L3 and OPAL experiments at LEP, and 600 thousand Z decays by the SLID experiment using a polarised beam at SLC. The measurements include cross-sections, forward-backward asymmetries and polarised asymmetries. The mass and width of the Z boson, m(Z) and Gamma(Z), and its couplings to fermions, for example the p parameter and the effective electroweak mixing angle for leptons, are precisely measured: m(Z) = 91.1875 +/- 0.0021 GeV, Gamma(Z) = 2.4952 +/- 0.0023 GeV, rho(l) = 1.0050 +/- 0.0010, sin(2)theta(eff)(lept) = 0.23153 +/- 0.00016. The number of light neutrino species is determined to be 2.9840 +/- 0.0082, in agreement with the three observed generations of fundamental fermions. The results are compared to the predictions of the Standard Model (SM). At the Z-pole, electroweak radiative corrections beyond the running of the QED and QCD coupling constants are observed with a significance of five standard deviations, and in agreement with the Standard Model. Of the many Z-pole measurements, the forward-backward asymmetry in b-quark production shows the largest difference with respect to its SM expectation, at the level of 2.8 standard deviations. Through radiative corrections evaluated in the framework of the Standard Model, the Z-pole data are also used to predict the mass of the top quark, m(t) = 173(+10)(+13) GeV, and the mass of the W boson, m(W) = 80.363 +/- 0.032 GeV. These indirect constraints are compared to the direct measurements, providing a stringent test of the SM. Using in addition the direct measurements of m(t) and m(W), the mass of the as yet unobserved SM Higgs boson is predicted with a relative uncertainty of about 50% and found to be less than 285 GeV at 95% confidence level.

Abstract: The decay rate of $\klpgg$ has been measured with the NA48 detector at the CERN SPS. A total of $2558$ $\klpgg$ candidates have been observed with a residual background of $3.2\%$. The branching ratio is determined to be $(1.36 \pm0.03_{(stat)} \pm0.03_{(syst)}\pm 0.03_{(norm)})\times10^{-6}$ and the vector coupling constant $a_v = -0.46 \pm0.03_{(stat)} \pm0.04_{(syst)}$. This result suggests that the CP-violation effects are dominating in the $\klpee$ decay. An upper limit for the $\klpgg$ decay rate in the two photon mass region $m_{\gamma\gamma} m_{\pi^0}$ is also given

Abstract: A measurement of the K_S lifetime is presented using data recorded by the NA48 experiment at the CERN-SPS during 1998 and 1999. The K_S lifetime is derived from the ratio of decay time distributions in simultaneous, collinear K_S and K_L beams, giving a result which is approximately independent of the detector acceptance and with reduced systematic errors. The result obtained is tau_S=(0.89598 +- 0.00048 +- 0.00051)x10^(-10) s, where the first error is statistical and the second systematic., 12 pages, 1 figure, to be published in Physics Letters B

Abstract: New measurements of the $\eta$ and $K^0$ masses have been performed using decays to 3$\pi^0$ with the NA48 detector at the CERN SPS. Using symmetric decays to reduce systematic effects, the results $M(\eta) = 547.843\pm0.051$~MeV/c$^2$ and $M(K^0) = 497.625\pm0.031$~MeV/c$^2$ were obtained.

Abstract: The direct CP violation parameter Re(ε′/ε) has been measured from the decay rates of neutral kaons into two pions using the NA48 detector at the CERN SPS. With 3.3 million KL → π0π0 events collected during the 1998 and 1999 running periods, a result of Re(ε′/ε) = (15.0 ± 2.7) × 10-4 has been obtained. The result combined with the published 1997 sample is Re(ε′/ε) = (15.3 ± 2.6) × 10-4.

Abstract: A new precise measurement of |V_{cb}| and of the branching ratio BR(\bar{B^0} -> D^{*+} \ell^- \bar{\nu_\ell}) has been performed using a sample of about 5000 semileptonic decays \bar{B^0} -> D^{*+} \ell^- \bar{\nu_\ell}, selected by the DELPHI detector at LEP I by tagging the soft pion from D^{*+} -> D^0 \pi^+. The results are: V_{cb}=(39.0 +/- 1.5 (stat.) ^{+2.5}_{-2.6} (syst. exp.) +/- 1.3 (syst. th.)) x 10^{-3} BR(\bar{B^0} -> D^{*+} \ell^- \bar{\nu_\ell})=(4.70 +/- 0.13 (stat.) ^{+0.36}_{-0.31} (syst. exp.))% The analytic dependences of the differential cross-section and of the Isgur Wise form factor as functions of the variable w = v_{B^0}.v_{D^*} have also been obtained by unfolding the experimental resolution., Comment: 26 pages, 5 figures, Accepted by Phys.

Abstract: The direct CP violation parameter Re(epsilon'/epsilon) has been measured from the decay rates of neutral kaons into two pions using the NA48 detector at the CERN SPS. With 3.3 million KL->pi0pi0 events collected during the 1998 and 1999 running periods, a result of Re(epsilon'/epsilon) = (15.0 +- 2.7)x10-4 has been obtained. The result combined with the published 1997 sample is Re(epsilon'/epsilon) = (15.3 +- 2.6)x10-4.

Abstract: A new precise measurement of |Vcb| and of the branching ratio BR(B̄0 → D*+ℓ-v̄ℓ) has been performed using a sample of about 5000 semileptonic decays B̄0 → D*+ℓ-v̄ℓ, selected by the DELPHI detector at LEP I by tagging the soft pion from D*+ → D0π+. The results are: Vcb = (39.0 ± 1.5 (stat.)-2.6 +2.5 (syst. exp.) ± 1.3 (syst. th.)) × 10-3, BR(B̄0 → D*+ℓ-v̄ℓ) = (4.70 ± 0.13 (stat.)-0.31 +0.36 (syst. exp.))%. The analytic dependencies of the differential cross-section and of the Isgur-Wise form factor as functions of the variable w = vB0 · vD* have also been obtained by unfolding the experimental resolution. © 2001 Published by Elsevier Science B.V.

Abstract: Muon pair production in the process e+e- → e+e- μ+μ- is studied using the data taken at LEP1 (√s ≃ mz) with the DELPHI detector during the years 1992-1995. The corresponding integrated luminosity is 138.5 pb-1. The QED predictions have been tested over the whole Q2 range accessible at LEP1 (from several GeV2/c4 to several hundred GeV2/c4) by comparing experimental distributions with distributions resulting from Monte Carlo simulations using various generators. Selected events are used to extract the leptonic photon structure function Fγ2. Azimuthal correlations are used to obtain information on additional structure functions, FγA and FγB, which originate from interference terms of the scattering amplitudes. The measured ratios FγA/Fγ2 and FγB/Fγ2 are significantly different from zero and consistent with QED predictions.

Abstract: Lifetime and oscillations of B0s mesons have been studied in events with a large transverse momentum lepton and a Ds of opposite electric charge in the same hemisphere, selected from about, 3.6 million hadronic Z0 decays accumulated by DELPHI between 1992 and 1995. The B0s lifetime and the fractional width difference between the two physical B0s states have been found to be: τB0s = (1.42+0.14-0.13(stat.) ± 0.03(syst.)) ps ΔΓB0s/ΓB0s < 0.46 at the 95% C.L. In the latter result it has been assumed that τB0s = τB0d. Using the same sample, a limit on the mass difference between the physical B0s states has been set: ΔmB0s > 7.4 ps-1 at the 95% C.L. with a corresponding sensitivity equal to 8.1 ps-1.

Abstract: A study of b semileptonic decays into D, Dπ± and D*π± final states is presented. The D0, D+ and D*+ mesons are exclusively reconstructed in Z decay data recorded from 1992 to 1995 in the DELPHI experiment at LEP. The overall branching fractions are measured to be: BR(b→ D0ℓ-νℓX) = (7.04 + 0.34 (stat) + 0.36 (syst.exp) + 0.17 (BRD))%, BR(b→ D+ℓ-νℓX) = (2.72 + 0.19 (stat) + 0.16 (syst.exp) + 0.18 (BRD))%, BR(b→ D*+ℓ-νℓX) = (2.75 + 0.17 (stat) + 0.13 (syst.exp) + 0.09 (BRD))%, where the D0 and D+ results include also contributions from D*0 and D*+ decays. A fit to the distribution of the π± impact parameter to the primary interaction vertex provides a measurement of the b semileptonic branching fractions into the D0π±X, D+π±X and D*+π±X final states. Assuming that single pion decay modes of B mesons dominate, the partial rates for B→Dπℓ-νℓ and B→D*πℓ-νℓ have been obtained, corresponding to a total branching fraction: BR(B→Dπℓ-νℓ) +BR(B→D*πℓ-νℓ) = (3.40 + 0.52 (stat) + 0.32 (syst))%. This result agrees well with the observed difference between the total B semileptonic branching fraction and the sum of the B→Dℓ-νℓ and B→D*ℓ-νℓ branching fractions. © 2000 Elsevier Science B.V.

Abstract: An update of the searches for charginos and gravitinos is presented, based on a data sample corresponding to the 158 pb^{-1} recorded by the DELPHI detector in 1998, at a centre-of-mass energy of 189 GeV. No evidence for a signal was found. The lower mass limits are 4-5 GeV/c^2 higher than those obtained at a centre-of-mass energy of 183 GeV. The (\mu,M_2) MSSM domain excluded by combining the chargino searches with neutralino searches at the Z resonance implies a limit on the mass of the lightest neutralino which, for a heavy sneutrino, is constrained to be above 31.0 GeV/c^2 for tan(beta) \geq 1., Comment: 22 pages, 8 figures

Abstract: Inclusive distributions of charged particles in hadronic W decays are experimentally investigated using the statistics collected by the DELPHI experiment at LEP during 1997, 1998 and 1999, at centre-of-mass energies from 183 to around 200 GeV. The possible effects of interconnection between the hadronic decays of two Ws are not observed. Measurements of the average multiplicity for charged and identified particles in qq̄ and WW events at centre-of-mass energies from 130 to 200 GeV and in W decays are presented. The results on the average multiplicity of identified particles and on the position ξ* of the maximum of the ξp = -log(2p/√s) distribution are compared with predictions of JETSET and MLLA calculations.

Abstract: The study of the directional dependence of two-particle correlations in the hadronic decays of the Z(0) boson is performed using the data collected by the DELPHI experiment in the 1992-1995 running periods. The comparison between the transverse, R-perpendicular to, and longitudinal, R-parallel to, correlation radii confirms the string model prediction that the transverse correlation length is smaller than the longitudinal one, with the measured values of R-perpendicular to = 0.53 +/- 0.08 fm and R-parallel to = 0.85 +/- 0.08 fm, for selected Z(0) –> q (q) over bar events.

Abstract: A search for stable and long-lived heavy charged particles was performed using the data taken by the DELPHI experiment at an energy of 189 GeV. The Cherenkov light detected in the Ring Imaging Cherenkov Detector and the ionisation loss measured in the Time Projection Chamber were used to identify heavy particles passing through the detector. No evidence for the production of such particles has been found, therefore exclusion limits at 95% confidence level were derived on the masses of left and right handed smuons and staus. The results were combined with previous DELPHI searches in this channel. Including previous DELPHI results, masses of left (right) handed stable smuons and staus can be excluded between 2 GeV/c^2 and 88 (87.5) GeV/c^2 at 95% CL., Comment: 9 pages, 2 figures

Abstract: Oscillations of B0s mesons have been studied in samples selected from about 3.5 million hadronic Z decays detected by DELPHI between 1992 and 1995. One analysis uses events in the exclusive decay channels: B0s -> Ds- pi+ or Ds- a1+ and B0s -> anti-D0 K- pi+ or anti-D0 K- a1+, where the D decays are completely reconstructed. In addition, B0s anti-B0s oscillations have been studied in events with an exclusively reconstructed Ds accompanied in the same hemisphere by a high momentum hadron of opposite charge. Combining the two analyses, a limit on the mass difference between the physical B0s states has been obtained: Delta(m_B0s) > 4.0 ps^{-1} at the 95% C.L. with a sensitivity of Delta(m_B0s) = 3.2 ps^{-1}. Using the latter sample of events, the B0s lifetime has been measured and an upper limit on the decay width difference between the two physical B0s states has been obtained: tau(B0s) = 1.53^{+0.16}_{-0.15}(stat.) +/- {0.07}(syst.) ps \Delta\Gamma(B0s)/\Gamma(B0s) < 0.69 at the 95% C.L. The combination of these results with those obtained using Ds+- lepton-+ sample gives: Delta(m_B0s) > 4.9 ps^{-1} at the 95% C.L. with a sensitivity of Delta(m_B0s) = 8.7 ps^{-1}. tau(B0s) = 1.46 +/- 0.11 ps and \Delta\Gamma(B0s)/\Gamma(B0s) < 0.45 at the 95% C.L., Comment: 42 pages, 13 figures

Abstract: The probability $P(c \rightarrow D^{*+})$ that a charm quark fragments into a $D^{*+}$ meson and the $c \rightarrow l^+$ semileptonic branching fraction were measured in $Z^0\ $ decay into $c\bar{c}$ events. \par % A double tag method based % on the detection of exclusively reconstructed $D$ mesons % accompanied by a slow pion or a lepton in the opposite hemisphere was used.\par From the analysis of 3.5 Million $Z^0\ $ events collected from 1992 to 1995, a sample of charm meson decays with $81\%$ $c\bar{c}$ purity was selected. % In this sample, a signal of $2371\pm140$ low momentum pions % originating from a $D^{*\pm}$ decay in the opposite hemisphere % was observed. The product of the $c \rightarrow D^{*+}$ fragmentation probability times the $D^{*+}\rightarrow D^0\pi^+$ branching fraction was measured to be: \begin{eqnarray*} P(c \rightarrow D^{*+})\cdot BR(D^{*+}\rightarrow D^0\pi^+) = 0.174\pm0.010(stat) \pm0.004(syst) \; . \end{eqnarray*} Using the world averaged value for $BR(D^{*+}\rightarrow D^0\pi^+)$, the fragmentation probability is inferred: \begin{eqnarray*} P(c \rightarrow D^{*+}) = 0.255\pm0.015(stat) \pm0.006(syst) \pm0.005 (syst.BR) \; . \end{eqnarray*} From the same sample, $1828\pm 51$ identified leptons in the opposite hemisphere were selected. From this sample, the charm semileptonic branching fraction was measured to be: \begin{eqnarray*} BR(c \rightarrow l^+) = 0.0958\pm0.0042(stat) \pm0.0028(syst) \; . \end{eqnarray*}

Abstract: Oscillations of Bs mesons have been studied in samples selected from about 3.5 million hadronic Z decays detected by DELPHI between 1992 and 1995. One analysis uses events in the exclusive decay channels: (Formula Presented),where the D decays are completely reconstructed. In addition,Bs 0-B̄̄s 0 oscillations have been studied in events with an exclusivelyreconstructed Ds accompanied in the same hemisphere bya high momentum hadron of opposite charge. Combining the two analyses,a limit on the mass difference between the physical Bs states has been obtained: ∆mB0s > 4.0 ps−1 at the 95% C.L. with a sensitivityof ∆mB0s = 3.2 ps−1. Using the latter sample of events,the Bs lifetime has been measured and an upper limit on the decay width difference between the two physical Bs states has been obtained: (Formula Presented) The combination of these results with those obtained using Dsℓ∓ sample gives: ∆mB0s > 4.9 ps−1 at the 95% C.L. with a sensitivityof ∆mB0s = 8.7 ps−1. © Springer-Verlag 2000.

Abstract: The $\tau$ polarisation has been studied with the ${\rm e^+e^-}\to \tau^+\tau^-$ data collected by the DELPHI detector at LEP in 1993, 1994 and 1995 around the Z resonance firstly through the exclusive decay channels ${\rm e}\nu\bar{\nu}$ , $\mu\nu\bar{\nu}$ , $\pi\nu$ , $\rho\nu$ and ${\rm a}_1\nu$ and secondly with an inclusive hadronic analysis which benefits from a higher efficiency and a better systematic precision. The results have been combined with those previously published on 1990 to 1992 DELPHI data, to produce results which reflect the full LEP-1 statistics. The fit of the $\tau$ polarisation dependence on the production angle yielded the polarisation parameters ${\cal A}_{_{\scriptstyle \!\tau}}=0.1359 \pm 0.0096$ and ${\cal A}_{_{\scriptstyle \!e}}=0.1382 \pm 0.0116$ . From these results the ratio of the vector and axial-vector effective couplings $\bar{v}_{\tau} / \bar{a}_{\tau} = 0.0683\pm0.0048$ and $\bar{v}_{\rm e} / \bar{a}_{\rm e} = 0.0694\pm0.0058$ have been derived, compatible with e $-\tau$ universality. With the assumption of lepton universality, the ratio of vector to axial-vector effective couplings for leptons $\bar{v}_l / \bar{a}_l = 0.0687\pm0.0037$ was obtained, implying a value of the effective weak mixing angle $\sin^{2}\theta^{\rm lept}_{\rm eff} = 0.23282\pm0.00092$ .

Abstract: The τ polarisation has been studied with the e+e- → τ+τ- data collected by the DELPHI detector at LEP in 1993, 1994 and 1995 around the Z resonance firstly through the exclusive decay channels evv̄, μvvμ, πv, ρv, and a1v and secondly with an inclusive hadronic analysis which benefits from a higher efficiency and a better systematic precision. The results have been combined with those previously published on 1990 to 1992 DELPHI data, to produce results which reflect the full LEP-1 statistics. The fit of the τ polarisation dependence on the production angle yielded the polarisation parameters Aτ = 0.1359 ± 0.0096 and Ae = 0.1382 ± 0.0116. From these results the ratio of the vector and axial-vector effective couplings v̄τ/āτ = 0.0683 ± 0.0048 and v̄e/āe = 0.0694 ± 0.0058 have been derived, compatible with e-τ universality. With the assumption of lepton universality, the ratio of vector to axial-vector effective couplings for leptons v̄ι/āι = 0.0687 ± 0.0037 was obtained, implying a value of the effective weak mixing angle sin2 θlepteff= 0.23282 ± 0.00092.

Abstract: The partial decay width $R_c$ of the $Z$ into $c\bar{c}$ quark pair and the number of charm quarks $n_c$ per $b$ decay are measured with the DELPHI detector at \mbox{LEP 1}. Particle identification provides clear $D^0$, $D^+$, $D_s^+$ and $\Lambda_c^+$ signatures. The charm hadron production rate is measured in each channel by a fit to the scaled energy, impact parameter information and the invariant mass spectrum. Two measurements of $R_c$ are presented, from the $D^{*+}$ production rate and from the overall charm counting, including strange charm baryon production, in $c\bar{c}$ events. The multiplicity $n_c$, which includes hidden $c\bar{c}$ and strange charm baryon production, is inferred from the charm counting in $b\bar{b}$ events. The final results are $R_c = 0.1665 \pm 0.0095$ and $n_c = 1.166 \pm 0.086$.

Abstract: The partial decay width Rc of the Z into cc̄ quark pair and the number of charm quarks nc per b decay are measured with the DELPHI detector at LEP 1. Particle identification provides clear D0, D+, D+s and Λ+c signatures. The charm hadron production rate is measured in each channel by a fit to the scaled energy, impact parameter information and the invariant mass spectrum. Two measurements of Rc are presented, from the D*+ production rate and from the overall charm counting, including strange charm baryon production, in cc̄ events. The multiplicity nc, which includes hidden cc̄ and strange charm baryon production, is inferred from the charm counting in bb̄ events. The final results are Rc = 0.1665 ± 0.0095 and nc-= 1.166 ± 0.086.

Abstract: {The ratio of the CKM quark-mixing matrix elements \textbackslash{}V-ub\textbackslash{}/\textbackslash{}V-cb\textbackslash{ } has been measured using B hadron semileptonic decays. The analysis uses the reconstructed mass M-X of the secondary hadronic system produced in association with an identified lepton. Since B --> X(u)l (v) over bar transitions are characterised by hadronic masses below those of the D mesons produced in B --> X(c)l (v) over bar transitions, events with a reconstructed value of M-X significantly below the D mass are selected. Further signal enrichments are obtained using the topology of reconstructed decays and hadron identification. A fit to the numbers of decays in the b --> u enriched and depleted samples with M-X above and below 1.6 GeV/c(2) and to the shapes of the lepton energy distribution in the B rest frame gives \textbackslash{}V-ub\textbackslash{}/\textbackslash{}V-cb\textbackslash{ } = 0.103 (+0.011)(-0.012) (stat.) +/- 0.016(syst.) +/- 0.010(model) and, correspondingly, a charmless semileptonic B decay branching fraction of BR(B --> X(u)l (v) over bar)= (1.57 +/- 0.35 (stat.) +/- 0.48(syst.) +/- 0.27(model)) x 10(-3).
