Abstract: Using data collected in the DELPHI detector at LEP-1, measurements of the inclusive tau branching ratios for decay modes containing one, three, or five charged particles have been performed, giving the following results: B_1 = B(\tau^- -> (particle)^- \geq 0pi^0 \geq 0K^0 \nu_\tau(\bar{\nu})) = (85.316 +/- 0.093 +/- 0.049)%; B_3 = B(\tau^- -> 2h^-h^+ \geq 0pi^0 \geq 0K^0 \nu_\tau) = (14.569 +/- 0.093 +/- 0.048)%; B_5 = B(\tau^- -> 3h^-2h^+ \geq 0pi^0 \geq 0K^0 \nu_\tau) = (0.115 +/- 0.013 +/- 0.006)%, where h is either a charged pi or K meson. The first quoted uncertainties are statistical and the second systematic., Comment: 32 pages, 10 figures, Accepted by Eur. Phys. J. C

Abstract: From the analysis of a data sample corresponding to an integrated luminosity of 4.63 pb-1 taken during the 1990 run of LEP at centre of mass energies between 88.2 GeV an 94.2 GeV, the tau decays {Mathematical expression} and their charge conjugates have been studied. The following branching ratios have been measured; {Mathematical expression}, {Mathematical expression}, Br(τ- → π- (K-)vτ)=11.9±0.7±0.7%, BR (τ- → ρ- vτ)= 22.4±0.8±1.3%, in good agreement with world averages. The measured electronic and muonic branching ratios lead to a measurement of the strong coupling constant, αs (mτ) = 0.26-0.12 +0.09. Extrapolating the αs value from mτ to mZ yields αs (mZ) = 0.109-0.028 +0.012. The average polarization Pτ of taus produced in Z → τs τs decays has also been measured using the above decay modes. The weighted mean of the polarizations obtained from the four decay modes is Pτ=-0.24±0.07. This value of Pτ gives, in the improved Born approximation, a ratio between the axial and vector coupling constants of the tau of υτ/aτ = 0.12 ± 0.04, and hence a value of the effective electroweak mixing parameter sin2 θW(mZ 2). © 1992 Springer-Verlag., 0, SCOPUS: ar.j, info:eu-repo/semantics/published

Abstract: 27 pages, 11 postscript figures, submitted to ICHEP 04; We present a preliminary measurement of the time-dependent CP-violating asymmetry in decays of neutral B mesons to the final states D*-+ pi+- using approximately 178 million BB events recorded by the BaBar experiment at the PEP-II e+e- storage ring. Events containing these decays are selected with a partial reconstruction technique, in which only the high-momentum pi+- from the B decay and the low-momentum pi-+ from the D*-+ decay are used. % We measure the amplitude of the asymmetry to be $-0.041 \pm 0.016 (stat.) \pm 0.010 (syst.)$ and determine bounds on $|\sin(2 \beta + \gamma)|$.

Abstract: 17 pages, 10 postscript figues, submitted to ICHEP2004; We present a preliminary measurement of the time-dependent CP-violating asymmetry in decays of neutral B mesons to the final states D*-+ pi+- using approximately 178 million BB events recorded by the BaBar experiment at the PEP-II e+e- storage ring. Events containing these decays are selected with a partial reconstruction technique, in which only the high-momentum pi+- from the B decay and the low-momentum pi-+ from the D*-+ decay are used. % We measure the amplitude of the asymmetry to be $-0.041 \pm 0.016 (stat.) \pm 0.010 (syst.)$ and determine bounds on $|\sin(2 \beta + \gamma)|$.

Abstract: With a sample of 88.8 BBbar pairs produced at PEP-II in e+e- annihilation through the Upsilon(4S) resonance and recorded with the BABAR detector, we search for the B+ --> K*0 Rho+ decay mode. A signal is observed for the first time with a significance of more than 5 sigma. We measure a preliminary branching fraction of BR(B+ --> K*0 Rho+)=[17.0 +-2.9 (stat) +-2.0 (syst) +0.0 -1.9 (non-resonant)] 10(-6). The "non-resonant" error corresponds to the uncertainty from non-resonant backgrounds not modeled in the fit. The measurement of the longitudinal-polarized component to this vector-vector penguin decay is of special interest. We measure fL= 0.79 +-0.08(stat) +-0.04 (syst) +- 0.02 (non-resonant). We measure the direct-CP-violating charge asymmetry in this mode to be A_CP = -0.14 +- 0.17 +- 0.04., Comment: 25 pages, 7 figures. contributed to ICHEP 2004

Abstract: The LHCb detector is a single arm spectrometer designed to exploit the large number of b-hadrons produced at the LHC in order to make precision studies of CP asymmetries and of rare decays in the B-meson system. It is therefore essential for the experiment that the detector configuration includes a particle identification system with high separation power between kaons and pions. We will present in this note the engineering solutions for the lightweight, high precision Ring Imaging Cherenkov detector, RICH2, of the spectrometer. The design is built around a large space frame used as a high stability support for the optical system and as a supporting structure for the magnetic shielding needed for the photon detectors. All material not essential for the operation of the detector is located outside the acceptance of the spectrometer. The space frame also defines the Cherenkov gas volume.

Abstract: We measure the branching fractions of the psi(2S) meson to the leptonic final states e+e- and mu+mu- relative to that for psi(2S)-->J/psi pi+pi-. The method uses psi(2S) mesons produced in the decay of B mesons at the Upsilon(4S) resonance in a data sample collected with the BABAR detector at the Stanford Linear Accelerator Center. Using previous measurements for the psi(2S)-->J/psi pi+pi- branching fraction, we determine the e+e- and mu+mu- branching fractions to be 0.0078+/-0.0009+/-0.0008 and 0.0067+/-0.0008+/-0.0007 respectively.

Abstract: The branching fractions of the exclusive decays $B^0\to K^{*0}\gamma$ and $B^+ \to K^{*+}\gamma$ are measured from a sample of $(22.74\pm 0.36)\times 10^6$ $B\bar B$ decays collected with the BABAR detector at the PEP II asymmetric $e^{+}e^{-}$ collider. We find ${\cal B}(B^0\to K^{*0}\gamma) = (4.23\pm 0.40({\rm stat.})\pm 0.22({\rm sys.}))\times 10^{-5}$, ${\cal B}(B^+\to K^{*+}\gamma) = (3.83\pm 0.62({\rm stat.})\pm 0.22({\rm sys.}))\times 10^{-5}$ and constrain the CP-violating charge asymmetry to be $-0.170 < A_{CP}(B \to K^*\gamma) < 0.082$ at 90% C.L.

Abstract: We have observed the decays B-->phi K and phi K^* in a sample of over 45 million B mesons collected with the BABAR detector at the PEP-II collider. The measured branching fractions are BF(B^+ --> phi K^+) = (7.7^{+1.6}_{-1.4}+/- 0.8) x 10^{-6}, BF(B^0 --> phi K^0) = (8.1^{+3.1}_{-2.5}+/- 0.8) x 10^{-6}, BF(B^+ --> phi K^{*+}) = (9.7^{+4.2}_{-3.4}+/- 1.7) x 10^{-6} and BF(B^0 --> phi K^{*0}) = (8.6^{+2.8}_{-2.4}+/- 1.1) x 10^{-6}. We also report the upper limit BF(B^+ --> phi pi^+) 1.4 x 10^{-6}$ (90% CL).

Abstract: We present a measurement of the decay amplitudes in B-->J/psi K^*(892) channels using 20.7 fb-1 of data collected at the Upsilon(4S) resonance with the BABAR detector at PEP-II. We measure a P-wave fraction R_perp = (16.0+/-3.2+/-1.4)% and a longitudinal polarization fraction (59.7+/-2.8+/-2.4)%. The measurement of a relative phase that is neither 0 nor pi, phi_ll = 2.50+/-0.20+/-0.08 radians, favors a departure from the factorization hypothesis. Although the decay B-->J/psi Kpi proceeds mainly via K^*(892), there is also evidence for K^*_2(1430) and Kpi S-wave contributions.

Abstract: A precise measurement of the strange quark forward-backward asymmetry used 3.2M multihadronic events around the Z° peak collected by the DELPHI experiment from 1992 to 1995. The ring imaging Cherenkov detectors in the barrel and end-cap regions identify high energy charged kaons which tag the s quark. The s quark asymmetry was measured at different centre-of-mass energies; m particular at the Z° pole A°ss̄ = 0.1008 ± 0.0113 (stat.) ± 0.0040 (syst.), (1) taking the expected d and u quark asymmetries from the Standard Model. The quark flavour fractions are assumed from the Standard Model and the fragmentation process is modelled by JETSET. From the s quark pole asymmetry the electroweak mixing angle was determined: sin2 θlepteff = 0.2321 ± 0.0029. (2) The parity violating coupling of the s quark to the Z was determined to be: As = 0.909 ± 0.102 (stat.) ± 0.036(syst.). (3).

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: Measurements of the trilinear gauge boson couplings $WW\gamma$ and $WWZ$ are presented from data taken by DELPHI in 1997 at an energy of 183 GeV. From a study of the reactions $e^+ e^- \to W^+ W^-, e^+ e^- \to We\nu$ and $e^+ e^- \to \nu\nu\gamma$, values are obtained for $\Delta g_{1}^{Z}$ and $\Delta K_{\gamma}$, the differences of the $WWZ$ charge coupling and of the $WW\gamma$ dipole couplings from their Standard Model values, and for $\lambda_{\gamma}$, the $WW\gamma$ quadrupole coupling. The observations are consistent with the predictions of the Standard Model.

Abstract: An update of the searches for charginos and neutralinos is presented, basedon a data sample corresponding to the 53.9 pb$^{-1}$ recorded by the DELPHIdetector in 1997, at a centre-of-mass energy of 183 GeV. No evidence for asignal was found. The lower mass limits are 4-5 GeV/$c^2$ higher than thoseobtained at a centre-of-mass energy of 172 GeV.The ($\mu$,M$_2$) domain excludedby combining the neutralino and chargino searches implies a limit on the mass ofthe lightest neutralino which, for a heavy sneutrino, is constrained to beabove 29.1 GeV/$c^2$ for $\tan{\beta}\geq$ 1.

Abstract: The rate $Z \rightarrow b\overline{b}b\overline{b}$ was measured using about $2 x 10^6$ hadronic decays collected by the DELPHI experiment in 1994 and 1995. Events were forced into 3-jets with $y_{min} > 0.06$ and a b-tag was required for every jet. The rate was measured to be: $R_{4b} = BR(Z \to b\overline{b}b\overline{b}) / BR(Z \to hadrons) = (6.0 +- 1.9(stat) +- 1.4(syst.)) x 10^{-4}$ where the invariant mass of every $b\overline{b}$ system is above twice the b quark mass. Using the value of $R_{4b}$ the probability of secondary production of a $b\overline{b}$ pair from a gluon per hadronic $Z$ decay, $g_{bb}$, was extracted and found to be: $g_{bb} = (3.3+-1.0(stat.) +- 0.8(syst.)) x 10^{-3}$.

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: 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 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).
