Abstract: DELPHI results are presented on the inclusive production of the neutral mesons$\rho^0$, $f_0(980)$, $f_2(1270)$, K$^{*0}_2(1430)$ and $f^{'}_2(1525)$ in hadronic Z$^0$ decays. They are based on about 2 million multihadronic events collected in 1994 and 1995, using the particle identification capabilities of the DELPHI Ring Imaging Cherenkov detectors and measured ionization losses in the Time Projection Chamber. The total production rates per hadronic Z$^0$ decay have been determined to be: $1.19 \pm 0.10$ for $\rho^0$; $0.164 \pm 0.021$ for $f_0(980)$;$0.214 \pm 0.038$ for $f_2(1270)$; 0:073 \pm 0:023 for $K^{*0}_2 (1430)$; and 0:012 \pm 0:006 for $f_{2}$(1525). The total production rates for all mesons and differential cross-sections for the $\rho^{0}$, $f_{0}$(980) and $f_{2}$(1270) are compared with the results of other LEP experiments and with models.

Abstract: The $\BB$ forward-backward asymmetry %, $\AFBbb$, has been determined from the average charge flow %, $\langle Q_{FB}\rangle$, measured in a sample of 3,500,000 hadronic Z decays collected with the DELPHI detector in 1992 - 1995. The measurement is performed in an enriched $\BB$ sample selected using an impact parameter tag and results in the following values for the $\BB$ forward-backward asymmetry: \begin {center} \begin{tabular}{ccl} \AFBbb (89.55 GeV) & = & $0.068\,\ \pm0.018\,\ (\mbox{stat.})\pm0.0013 (\mbox{syst.})$ \\ \AFBbb (91.26 GeV) & = & $0.0982\pm0.0047(\mbox{stat.})\pm0.0016(\mbox{syst.})$ \\ \AFBbb (92.94 GeV) & = & $0.123\,\ \pm0.016\,\ (\mbox{stat.})\pm0.0027(\mbox{ syst.})$ \\ \end{tabular} \end{center} %at an average center of mass energy of 91.251\, GeV . % The $\BB$ charge separation %, $\db$, required for this analysis is directly measured in the b tagged sample, while the other charge separations %, $\ddusc$, are obtained from a fragmentation model precisely calibrated to data. % The effective weak mixing angle %, $\sweff$, is deduced from the measurement to be: \begin {center} \begin{tabular}{ccl} \sweff & =& $ 0.23186\pm0.00083$ \end{tabular} \end{center}

Abstract: The partial decay width of the Z to $\bb$ quark pairs has beenmeasured by the DELPHI detector at LEP using data taken in the years1992 to 1995.Decays of b-hadrons were tagged by several methods usingtracks with large impact parameters and/or reconstructed secondary vertices, complemented by event shape variables.Combining these methods in a multivariate analysis the value\[\frac{\Gamma({\mathrm Z \rightarrow \bb}) }{ \Gamma({\mathrm {Z \rightarrow had}}) } = 0.21634 \pm 0.00067({\mathrm {stat}}) \pm 0.00060 ({\mathrm {syst}})\]was obtained, where the ${\mathrm c} \bar {\mathrm c}$ production fractionwas fixed to its Standard Model value.

Abstract: The hadronic structure of the decay of the $\tau$ lepton to three charged particles, $\tau\rightarrow 3\pi\nu_\tau$, is studied using data collected by the DELPHI detector at LEP between 1992 and 1995. The invariant mass of the $3\pi$ system, $m_{3\pi}$, is fitted using the models of Kühn and Santamaria, Isgur Morningstar and Reader, and Feindt. The $3\pi$ mass spectrum and the Dalitz projections are compared with each model. Below \mbox{$m_{3\pi}^2 = 2.3~ {\GeV}^2$}, all are in good qualitative agreement. Above \mbox{$m_{3\pi}^2 = 2.3~ {\GeV}^2$}, anomalous behaviour is observed, consistent with the existence of a hitherto unseen decay mode of the $\tau$ through a radial excitation of the $a_1$ meson.

Abstract: The total and the differential cross-sections for the reaction $e^+e^-\rightarrow \gamma\gamma(\gamma)$ have been measured with the DELPHI detector at LEP % with at centre-of-mass energies from 1 30 %, 136, 161, 172 and to 183 GeV for an integrated luminosity of 78.19.~pb$^{-1}$. %CR An agreement with the QED predictions was found and consequently The results agree with the QED prediction s. The lower limits (obtained including previously published results at the $\Zzero$ energies) on the QED cutoff parameters are $\Lambda_{+} > 253$~GeV and $\Lambda_{-} > 225$~GeV and the lower bo und on the mass of an excited electron with an effective coupling constant $\lambda_{\gamma} = 1$ is 231~GeV/$c^2$. %Upper limits on the branching ratios for the decays ${\rm Z}^0\rightarrow %\gam ma\gamma$, ${\rm Z}^0\rightarrow \pi^0\gamma$, % ${\rm Z}^0\rightarrow \eta\gamma$ %and ${\rm Z}^0\rightarrow \gamma\gamma\gamma$ have been determined to be 2.5 % $\times$ $10^{-5}$, 2.5 $\times$ $ 10^{-5}$, % 4.0 $\times$ $10^{-5}$, %and 9.1 $\times$ $10^{-4}$ respectively. All the limits are at the 95$\%$ confidence level.

Abstract: This paper presents results on charged Higgs boson production, based on LEP data collected at $\sqrt{s} = 172$ GeV, that complement the previous DELPHI results obtained at centre of mass energies up to 161 GeV. %The analysis is based on LEP data collected at $\sqrt{s} = 172$ GeV. The charged Higgs bosons are assumed to be pair produced and to decay either into a quark pair %, identified as cs, or into $\tau\nu_{\tau}$. The three different possible final states are included in the analysis. Data from ring imaging Cherenkov and microvertex detectors are used to identify the quarks as a cs pair. %No significant signal was found. The number of candidates found is compatible with the background expected from standard processes. Combining the results of the present analysis with those of the previous analysis at lower energies, a new lower mass limit for the charged Higgs boson is set at 54.5 GeV/$c^2$.

Abstract: The DELPHI experiment at LEP uses Ring Imaging Cherenkov detectors for particle identification. The good understanding of the RICH detectors allows the identification of charged pions, kaons and p rotons, covering the full momentum range from \mbox{$0.7\! \!p\! \! 45.6~\gevc$}. The $\pipm$,~$\kapm$, p and $\pbar$ normalised production rates, their differential cross sections, multiplicities a nd the maxima $\xipst$ of the \mbox{$\xip=\ln(1/\xp)$} distributions are measured for three event samples $\zqqbar$, ~$\zbbbar$ and $\zudsbar$, selected from \mbox{$\sim\!1\,400\, 000$}~$\zzero$ deca ys collected by \delphi in 1994. The results are compared to the predictions of the \jetset string fragmentation model and the \herwig cluster fragmentation model. The Modified Leading Logarithm Ap proximation with Local Parton-Hadron Duality is tested. The $\xipst$ dependence on the primary quark flavour is investigated and quantified for the different particle distributions. The $\pipm$, $ \kapm$, p and $\pbar$ multiplicities are measured with precisions from $\pm4$\%~to~$\pm6$\%. For the $\zqqbar$ and $\zbbbar$ event samples, these improve on previous measurements. The $\pipm$, $\k apm$, p and $\pbar$ multiplicities for $\zudsbar$ are presented for the first time.

Abstract: The data collected by DELPHI in 1996 have been used to measure the average charged particle multiplicities and dispersions in $q\bar{q}$ events at centre-of-mass energies of $\sqrt{s}=161$~GeV and $\sqrt{s}=172$~GeV, and the average charge multiplicity in WW events at $\sqrt{s}=172$~GeV. The multiplicities in $q\bar{q}$ events are consistent with the evolution predicted by QCD. The dispersions in the multiplicity distributions are consistent with Koba-Nielsen-Olesen (KNO) scaling. The average multiplicity of charged particles in hadronic W decays has been measured for the first time; its value, $19.23 \pm 0.74 (stat+syst)$, is consistent with that expected for an $e^+e^-$ interaction at a centre-of-mass energy equal to the W mass. The charged particle multiplicity in W decays shows no evidence of effects of colour reconnection between partons from different W's at the present level of statistics.

Abstract: A search for stable or long-lived heavy charged particles in $e^+e^-$ interactions at energies of 130-136, 161 and 172 GeV has been performed using the data taken by the DELPHI experiment at LEP. The search is based on particle identification provided by the Time Projection Chamber and the Ring Imaging Cherenkov detector. Upper limits at 95\% confidence level are derived on the cross-section for heavy long-lived pair-produced charge $\pm e$ and $\pm 2/3e$ particles in the range of 0.4-2.3 pb for masses from 45 to 84 GeV/$c^2$. Within supersymmetric extensions of the Standard Model, long-lived charginos with masses from 45 to 84 (80)~GeV/$c^2$ for high (low) sneutrino masses can be excluded at 95\% confidence level. %Mass limits for long-lived sleptons are obtained. %For selectrons no general mass limits can be given. Left-handed (right-handed) long-lived or stable smuons and staus with masses between 45 and 68 (65)~GeV/$c^2$ can be excluded at 95\% confidence level.

Abstract: Correlations between pions from different Ws in $e^+e^- rightarrow$W$^+$W$^-$ events are studied using data collected by the DELPHI detector at LEP running at a centre-of-mass energy of 172 GeV in 1996. At the present level of statistics, no enhancement of the correlation function above that expected from a pair of uncorrelated Ws is observed at small values of the four-momentum difference of the pions.

Abstract: ${B}^0_d$ meson oscillations are measured in hadronic $\Zz$ decays using the charge of a lepton or the mean charge of an event hemisphere to sign the presence of a $b$ or a $\overline{b}$ quark when it is produced, and using the charge of a lepton emitted at large p$_t$ or of a D$^{\ast \pm}$ to sign the presence of a B or a $\bar{\mbox{B}}$ meson when it decays. With 3.2 million hadronic $\Zz$ decays registered by DELPHI between 1991 and 1994, the mass difference $\Delta m_d$ between the two physical $\mbox{B}^0_d$ states is measured in four channels: \begin{eqnarray} \Delta m_d &=& 0.523 \pm 0.072 \pm 0.043 ~ \mbox{ps}^{-1}~~(\Dstar - Q_{hem})\nonumber \\ \Delta m_d &=& 0.493 \pm 0.042 \pm 0.027 ~ \mbox{ps}^{-1}~~(\ell - Q_{hem})\nonumber \\ \Delta m_d &=& 0.499 \pm 0.053 \pm 0.015 ~ \mbox{ps}^{-1}~~((\pimora-\ell)-Q_{hem})\nonumber \\ \Delta m_d &=& 0.480 \pm 0.040 \pm 0.051 ~ \mbox{ps}^{-1}~~(\ell - \ell).\nonumber \end{eqnarray} Taking into account the statistical overlap between these measurements and the common systematic uncertainties, the combined result is: \Delta m_d = 0.496 \pm 0.034 ~ \mbox{ps}^{-1}.

Abstract: Inclusive charged particle and event shape distributions are measured using 321 hadronic events collected with the DELPHI experiment at LEP at effective centre of mass energies of 130 to 136 GeV. These distributions are presented and compared to data at lower energies, in particular to the precise Z data. Fragmentation models describe the observed changes of the distributions well. The energy dependence of the means of the event shape variables can also be described using second order QCD plus power terms. A method independent of fragmentation model corrections is used to determine $\alpha_s$ from the energy dependence of the mean thrust and heavy jet mass. It is measured to be: % %\alpha_s(M_{\rm Z}) = 0.116 \pm 0.002_{exp} \pm 0.007_{theo} % % %\noindent %from the data up to Z energies and \alpha_s(133\mbox{ GeV}) = 0.116 \pm 0.007_{exp} {^{+0.005}_{-0.004}}_{theo} %\noindent from the high energy data.

Abstract: A search with the DELPHI detector at LEP for excited leptons ($e^*$, $\mu^*$, $\tau^*$ and $\nu^*$) decaying through $\gamma$, W or Z transitions is reported. The data used correspond to an integrated luminosity of 10 pb$^{-1}$ at an $e^+e^-$ centre-of-mass energy of 161 GeV. The search for pair produced excited leptons established the limits $m_{e^*} > 79.6 $ GeV/$c^2$, $m_{\mu^*} > 79.6$ GeV/$c^2$, $m_{\tau^*} > 79.4$ GeV/$c^2$ and $m_{\nu^*} > 56.4$ GeV/$c^2$ at 95\% confidence level, assuming that the SU(2) and U(1) couplings of excited leptons are in the same ratio as for normal leptons and considering both left and right-handed components. Limits corresponding to other assumptions are also given. The search for single excited lepton production established upper limits on the ratio $\lambda/m_{\ell^*}$ of the coupling of the excited lepton to its mass.

Abstract: Using data accumulated by DELPHI during the November 1995 LEP run at 130~GeV -- 136~GeV, searches have been made for events with jets or leptons in conjunction with missing momentum. The results are interpreted in terms of limits on the production of neutralinos, scalar leptons, and scalar quarks.

Abstract: A search for pair production of the lightest chargino at $\rs=$ 130.4 and 136.3~GeV has been carried out using the data sample corresponding to the 5.92~${\rm pb}^{-1}$ recorded by the DELPHI detector during the high energy run of LEP in the last period of 1995. The theoretical reference model has been the Mi\-ni\-mal Supersymmetric Standard Model with R-parity conservation. The three topologies expected for the decay of a pair of charginos, namely two acoplanar leptons plus missing energy (\ll), two jets and an isolated lepton plus missing energy (\jjl) and missing energy in a hadronic environment (\jj), were investigated. No evidence of a signal was found. Lower mass limits were derived for various scenarios, including the case of a low mass difference between the chargino and the neutralino and of a light sneutrino. The mass limits range between 56.3~GeV/${\rm c}^2$ and the kinematic limit.

Abstract: Reconstructed \lam\ baryon decays and photon conversions in DELPHI are used to measure the \sig\ production rate from hadronic Z^0 decays at LEP. The number of \sig\ decays per hadronic Z decay is found to be: \begin{center} < \sig + \sigb > = \wffe{0.070}{0.010}{0.010 }{}. \end{center} \bigskip The \Omega^- production rate is similarly measured to be: \begin{center} < \Omega^- + \overline{\Omega}^+ > = \wffe{0.0014}{0.0002}{0.0004}{} \end{center} by a combination of methods using constrained fits to the whole decay chain and particle identification.

Abstract: Semileptonic decays B \rightarrow D^{*-} \ell^+ \nu X were selected from a sample of 3.1 million hadronic Z decays collected by the DELPHI detector at LEP. A topological search for semileptonic B decays to resonant %(D^{**}) and non-resonant D^{*-} \pi^{+} states was performed and the ratio of the branching fractions: \frac {Br ({\mathrm{B} \rightarrow {\mathrm D}^{*-}} \ell^+ \nu X)} {Br({\mathrm{B} \rightarrow {\mathrm D}^{*-}} \ell^+ \nu X) + Br( {\mathrm{B}^0 \rightarrow \mathrm{D}^{*-}} \ell^+ \nu)} = 0.19 \pm 0.10({\mathrm{stat}}) \pm 0.06({\mathrm{syst}}) was determined. Taking into account this contribution, %DB the differential production fraction of the decay the differential decay width of {\mathrm{B}^{0} \rightarrow \mathrm{D}^{*-}} \ell^+ \nu was measured as a function of the momentum transfer from the B to the D^{*-} in two separate analyses, using exclusive and inclusive methods of D^{*-} reconstruction. The distributions were fitted %DB with a linear function over the full momentum transfer range to extract the product of \mathrm{|V_{cb}|} times the normalization of the decay form factor F(q^2_{max}): F(q^2_{max})\mathrm{|V_{cb}|} = (35.0 \pm 1.9({\mathrm{stat}}) \pm 2.3({\mathrm{syst}}) )~\cdot~10^{-3}. The value of \mathrm|V_{cb}| was computed using theoretical calculations of F(q^2_{max}), giving: {\mathrm{|V_{cb}|}} = (38.5 \pm 2.1({\mathrm{stat}}) \pm 2.5({\mathrm{syst}}) \pm 1.7({\mathrm{theory}}))~\cdot~10^{-3}. The total branching fraction Br(\mathrm{B}^{0} \rightarrow D^{*-} \ell^+ \nu) was determined to be: Br ({\mathrm{B}^0 \rightarrow \mathrm{D}^{*-}} \ell^+ \nu) = (5.47 \pm 0.16({\mathrm{stat}}) \pm 0.67({\mathrm{syst}})) \%.

Abstract: Data are presented on the reaction \epem~\into~\gamma + no other detected particle at center-of-mass energies, \sqs = 89.48 GeV, 91.26 GeV and 93.08 GeV. The cross section for this reaction is related directly to the number of light neutrino generations which couple to the \zz boson, and to several other phenomena such as excited neutrinos, the production of an invisible `X' particle, a possible magnetic moment of the tau neutrino, and neutral monojets. Based on the observed number of single photon events, the number of light neutrinos which couple to the \zz is measured to be N_\nu = 3.15 \pm 0.34. No evidence is found for anomalous production of energetic single photons, and upper limits at the 95\% confidence level are determined for excited neutrino production (BR < 4-9 \times 10^{-6}), production of an invisible `X' particle (\sigma < 0.1 pb), and the magnetic moment of the tau neutrino (< 5.2 \times 10^{-6} \mu_B). No event with the topology of a neutral monojet is found, and this corresponds to the limit \sigma < 0.044/\epsilon pb at the 95\% confidence level, where \epsilon is the unknown overall monojet detection efficiency.

Abstract: An analysis is presented of inclusive \pi^0 production in Z^0 decays measured with the DELPHI detector. At low energies, \pi^0 decays are reconstructed by \linebreak using pairs of converted photons and combinations of converted photons and photons reconstructed in the barrel electromagnetic calorimeter (HPC). At high energies (up to x_p = 2 \cdot p_{\pi}/\sqrt{s} = 0.75) the excellent granularity of the HPC is exploited to search for two-photon substructures in single showers. The inclusive differential cross section is measured as a function of energy for {q\overline q} and {b \bar b} events. The number of \pi^0's per hadronic Z^0 event is N(\pi^0)/ Z_{had}^0 = 9.2 \pm 0.2 \mbox{(stat)} \pm 1.0 \mbox{(syst)} and for {b \bar b}~events the number of \pi^0's is {\mathrm N(\pi^0)/ b \overline b} = 10.1 \pm 0.4 \mbox{(stat)} \pm 1.1 \mbox{(syst)} . The ratio of the number of \pi^0's in b \overline b events to hadronic Z^0 events is less affected by the systematic errors and is found to be 1.09 \pm 0.05 \pm 0.01. The measured \pi^0 cross sections are compared with the predictions of different parton shower models. For hadronic events, the peak position in the \mathrm \xi_p = \ln(1/x_p) distribution is \xi_p^{\star} = 3.90^{+0.24}_{-0.14}. The average number of \pi^0's from the decay of primary \mathrm B hadrons is found to be {\mathrm N} (B \rightarrow \pi^0 \, X)/\mbox{B hadron} = 2.78 \pm 0.15 \mbox{(stat)} \pm 0.60 \mbox{(syst)}.

Abstract: The hadronic photon structure function F_{2}^{\gamma} has been measured in the Q^{2} range from 4 to 30~GeV^2/c^{4} and down to x values of order 0.001, using data taken with the DELPHI detector at LEP between 1991 and 1993. A comparison is made with several F_{2}^{\gamma} parameterizations with special emphasis on their low x behaviour. A result on the Q^{2} evolution of F_{2}^{\gamma} is presented.

Abstract: This letter reports the results of the measurement of single photon production in the reaction $e^+e^- \rightarrow \gamma +$ invisible particles at centre-of-mass energies $\sqrt{s}=$~130 and 136 GeV and an integrated luminosity of 5.83~pb$^{-1}$, collected with the DELPHI detector at LEP. %No anomalous signal has been observed. The contribution from The signal is compatible with the prediction of the Standard Model for the process $ e^+e^- \rightarrow \nu \bar{\nu}\gamma $, and the number of neutrino families has been determined to be $N_{\nu}=3.1 \pm 0.6 $. Limits have been derived on anomalous neutral gauge boson couplings and on compositeness in the framework of a specific model.

Abstract: A measurement of the mass difference, \Delta m_d, between the two physical \mbox{B}^0_d states has been obtained from the analysis of the impact parameter distribution of a lepton emitted at large transverse momentum (p_t) relative to the jet axis and from the analysis of the flight distance distribution of secondary vertices tagged by either a high p_t lepton or an identified kaon. In the opposite hemisphere of the event, the charge of the initial quark has been evaluated using a high p_t lepton, a charged kaon or the mean jet charge. With 1.7 million hadronic Z^0 decays recorded by DELPHI between 1991 and 1993, \Delta m_d is found to be: \Delta m_d = 0.531^{+0.050}_{-0.046} ~(stat.) \pm 0.078 ~(syst.) ~ {\mathrm{ps}}^{-1} \, .

Abstract: An upper limit for $BR(Z^0\rightarrow3g)$ is obtained from a correlation method, which distinguishes statistically between quark and gluon jets by using the difference in their charged particle multiplicity distributions. From the sample of threefold symmetric three--jet events collected by the DELPHI experiment at LEP during 1991-1994, the 95\% confidence level upper limit is deduced to be: $BR(Z^0\rightarrow3g)\leq 1.6\times 10^{-2}$ for the JADE and $BR(Z^0\rightarrow3g)\leq 1.5\times 10^{-2}$ for the DURHAM jet--finder.

Abstract: Rare decays of beauty particles were studied in several charmless modes using the data collected with the DELPHI detector at LEP from 1991 to 1994. These decays are mediated by both tree level $b \rightarrow u$ and one-loop penguin $b \rightarrow s$, $d$ transitions. Evidence for charmless $B$ decays was obtained in two body hadronic modes. The branching ratios of $B^{0}_{d,s}$ to $\pi^+ \pi^-$ or $K^+ \pi^-$ and $B^{-}_{u}$ to $\rho^0 \pi^-$ or $K^{*0} \pi^-$ were found to be $(2.8 ^{+1.5}_{-1.0} \pm 0.2) \times 10^{-5}$ and $(1.7 ^{+1.2}_{-0.8} \pm 0.2) \times 10^{-4}$ respectively. The fraction of these decays with a charged kaon in the final state that is not from the spectator $s$ quark, was measured to be $0.58 \pm 0.18$. Upper limits were set at 90\% confidence level on the branching ratios %for other two body modes including the $\Lambda_b^0\to pK^-$ decay and for three and four body charmless hadronic decays in the range of \mbox{$(1 - 3)\times10^{-4}$}, for inclusive radiative $b \rightarrow s \gamma$ decays at $5.4\times10^{-4}$, for the exclusive radiative decays $B_{d}^{0} \rightarrow K^*(892)^0\gamma$ and $B_{s}^{0} \rightarrow \phi(1020) \gamma$ at $2.1\times10^{-4}$ and $7.0\times10^{-4}$ respectively, and for dineutrino decays, $b \rightarrow s \nu \bar \nu$, in the exclusive channels $B_{d}^{0} \rightarrow K^*(892)^0 \nu \bar \nu$ and $B_{s}^{0} \rightarrow \phi(1020) \nu \bar \nu$ at 1.0 $\times$ 10$^{-3}$ and 5.4 $\times$ 10$^{-3}$ respectively. The limits on dineutrino decays constrain theories with a new $U(1)$ gauge boson coupling predominantly to the third family of fermions.

Abstract: From the data collected by DELPHI at LEP in autumn 1995, the multiplicity of charged particles at a hadronic energy of 130 GeV has been measured to be = 23.84 \pm 0.51 (stat) \pm 0.52 (syst). When compared to lower energy data, the value measured is consistent with the evolution predicted by QCD with corrections at next-to-leading order, for a value \alpha_s(130 {\mathrm{GeV}}) = 0.105 \pm 0.003 (stat) \pm 0.008 (syst).

Abstract: A measurement of B meson lifetimes is presented using data collected from 1991 to 1993 by the DELPHI detector at the LEP collider. Samples of events with a D meson and a lepton in the same jet are selected where \overline{\mathrm{D}}^0 \ell^+ and \mathrm{D}^{*-} \ell^+ events originate mainly from the semileptonic decays of B^+ and B^0 mesons, respectively. From the reconstructed B decay length and the estimated B momentum, taking into account the dilution due to B decays into \overline{\mathrm{D}}^{**} \ell^+ \nu, the following B meson lifetimes and lifetime ratio are measured: \begin{eqnarray*} \tau(\mathrm{B}^+) &=& 1.61^{+0.16}_{-0.16} \;(\mathrm{stat}.) \pm 0.12 \;(\mathrm{syst.}) \;\mathrm{ ps} \\ \tau(\mathrm{B}^0) &=& 1.61^{+0.14}_{-0.13} \;(\mathrm{stat}.) \pm 0.08 \;(\mathrm{syst.}) \;\mathrm{ ps} \\ \tau(\mathrm{B}^+) / \tau(\mathrm{B}^0) &=& 1.00^{+0.17}_{-0.15} \;(\mathrm{stat.}) \pm 0.10 \;(\mathrm{syst.}) \end{eqnarray*} and an average lifetime of B^+ and B^0 mesons is obtained: \begin{eqnarray*} \tau(\mathrm{B}) = 1.61^{+0.08}_{-0.07} \;\mathrm{(stat.)} \pm 0.05 \;\mathrm{(syst.) \;ps} \end{eqnarray*}

Abstract: During the LEP running periods in 1990 and 1991 DELPHI has accumulated approximately 450000 Z0 decays into hadrons and charged leptons. The increased event statistics coupled with improved analysis techniques and improved knowledge of the LEP beam energies permit significantly better measurements of the mass and width of the Z0 resonance. Model independent fits to the cross sections and leptonic forward-backward asymmetries yield the following Z0 parameters: the mass and total width M(Z) = 91.187 +/- 0.009 GeV, GAMMA(Z) = 2.486 +/- 0.012 GeV, the hadronic and leptonic partial widths GAMMA(had) = 1.725 +/- 0.012GeV, GAMMA(l) = 83.01 +/- 0.52 MeV, the invisible width GAMMA(inv) = 512 +/- 10 MeV, the ratio of hadronic to leptonic partial widths R(l) = 20.78 +/- 0.15, and the Born level hadronic peak cross section sigma0 = 40.90 +/- 0.28 nb. Using these results and the value of alpha(s) determined from DELPHI data, the number of light neutrino species is determined to be 3.08 +/- 0.05. The individual leptonic widths are found to be: GAMMA(e) = 82.93 +/- 0.70 MeV, GAMMA(mu) = 83.20 +/- 1.11 MeV and GAMMA(tau) = 82.89 +/- 1.31 MeV. Using the measured leptonic forward-backward asymmetries and assuming lepton universality, the squared vector and axial-vector couplings of the Z0 to charged leptons are found to be g(V)l2 = (1.47 +/- 0.51) x 10(-3) and g(A)l2 = 0.2483 +/- 0.0016. A full Standard Model fit to the data yields a value of the top mass m(t) = 115(-82)+52 (expt.)-24(+23) (Higgs) GeV, corresponding to a value of the weak mixing angle sin2 theta(eff)lept = 0.2339 +/- 0.0015(expt.)-0.0004(+0.0001) (Higgs). Values are obtained for the variables S and T, or epsilon1 and epsilon3 which parameterize electroweak loop effects.

Abstract: The total and the differential cross sections for the reaction e+e- → γγ(γ) have been measured with the DELPHI detector at LEP using an integrated luminosity of 36.9 pb-1. The results agree with the QED predictions and consequently there is no evidence for non-standard channels with the same experimental signature. The lower limits obtained on the QED cutoff parameters are Λ+ > 143 GeV and Λ- > 120 GeV, and the lower bound on the mass of an excited electron with an effective coupling constant λγ = 1 is 132 GeV/c2. Upper limits on the branching ratios for the decays Z0 → γγ, Z0 → π0γ, Z0 → ηγ and Z0 → γγγ have been determined to be 5.5 × 10-5, 5.5 × 10-5, 8.0 × 10-5, and 1.7 × 10-5 respectively. All the limits are at the 95% confidence level.

Abstract: Strange beauty meson Bs0 have been reconstructed through exclusive hadronic final states, using the data collected in 1992 by the DELPHI experiment at the LEP collider. The analysis relies on the combined use of accurate tracking and of the hadron identification capabilities of DELPHI. Three Bs0 decay candidates have been selected over a negligible background using theDs−π+, Ds−a1+ (1260) and View the MathML source decay modes, with identified kaons in the final state. The Bs0 meson mass is measured to be mBs = (5374± 16± 2) MeV/ c2.

Abstract: A search for the Standard Model Higgs boson was performed in the data sample of around 1 million hadronic Z0 decays recorded in 1991 and 1992 with the DELPHI detector at LEP. The Higgs boson was searched for through its production in association with either neutrinos, electrons or muons. Four low mass events remain after the selections in the charged leptonic channels, that are likely to be due to background, especially four fermion processes. These results restrict the mass of the Standard Model Higgs boson to be larger than 55.7 GeV/c2 at the 95% confidence level.

Abstract: Distributions of event shape variables obtained from 120600 hadronic Z decays measured with the DELPHI detector are compared to the predictions of QCD based event generators. Values of the strong coupling constant αs are derived as a function of the renormalization scale from a quantitative analysis of eight hadronic distributions. The final result, αs(MZ), is based on second order perturbation theory and uses two hadronization corrections, one computed with a parton shower model and the other with a QCD matrix element model. © 1992 Springer-Verlag.
