Abstract

An updated analysis using about 1.5 million events recorded at $\sqrt{s} = M_Z$ with the DELPHI detector in 1994 is presented. Eighteen infrared and collinear safe event shape observables are measured as a function of the polar angle of the thrust axis. The data are compared to theoretical calculations in ${\cal O} (\alpha_s^2)$ including the event orientation. A combined fit of $\alpha_s$ and of the renormalization scale $x_{\mu}$ in $\cal O(\alpha_s^2$) yields an excellent description of the high statistics data. The weighted average from 18 observables including quark mass effects and correlations is $\alpha_s(M_Z^2) = 0.1174 \pm 0.0026$. The final result, derived from the jet cone energy fraction, the observable with the smallest theoretical and experimental uncertainty, is $\alpha_s(M_Z^2) = 0.1180 \pm 0.0006 (exp.) \pm 0.0013 (hadr.) \pm 0.0008 (scale) \pm 0.0007 (mass)$. Further studies include an $\alpha_s$ determination using theoretical predictions in the next-to-leading log approximation (NLLA), matched NLLA and $\cal O(\alpha_s^2$) predictions as well as theoretically motivated optimized scale setting methods. The influence of higher order contributions was also investigated by using the method of Pad\'{e} approximants. Average $\alpha_s$ values derived from the different approaches are in good agreement., Comment: 48 pages

Abstract

A search for pair-produced charged Higgs bosons was performed in the high energy data collected by the DELPHI detector at LEP II at centre-of-mass energies from 189 GeV to 202 GeV. The three different final states, τvτv, cs̄c̄s and cs̄τv were considered. New methods were applied to reject wrong hadronic jet pairings and for the tau identification, where a discriminator based on tau polarisation and polar angles was used. No excess of data compared to the expected Standard Model processes was observed and the existence of a charged Higgs boson with mass lower than 71.5 GeV/c2 is excluded at the 95% confidence level. © 2002 Published by Elsevier Science B.V., SCOPUS: ar.j, info:eu-repo/semantics/published

Abstract

A search for pair-production of neutralinos at a LEP centre-of-mass energy of 189 GeV gave no evidence for a signal. This limits the neutralino production cross-section and excludes regions in the parameter space of the Minimal Supersymmetric Standard Model (MSSM)., Comment: 24 pages, 10 figures, Accepted by Eur.

Abstract

Searches for pair production of gauginos and squarks in e+e- collisions at a centre-of-mass energy of 189 GeV have been performed on data corresponding to an integrated luminosity of 158 pb^{-1} collected by the DELPHI detector at LEP. The data were analyzed under the assumption of non-conservation of R-parity through a single dominant Ubar Dbar Dbar coupling between squarks and quarks. Typical final states contain between 4 and 10 jets with or without additional leptons. No excess of data above Standard Model expectations was observed. The results were used to constrain domains of the MSSM parameter space and derive limits on the masses of supersymmetric particles. The following mass limits at 95% CL were obtained from these searches: neutralino mass: m_{\tilde{\chi^0_{1}}} \geq 32 GeV chargino mass: m_{\tilde{\chi^+_{1}}} \geq 94 GeV stop and sbottom mass (indirect decay) with \Delta M > 5 GeV: m_{\tilde{t_1}} \geq 74 GeV, for \Phi_{mix}=0 rad m_{\tilde{t_1}} \geq 59 GeV, for \Phi_{mix}=0.98 rad m_{\tilde{b_1}} \geq 72 GeV, for \Phi_{mix}=0 rad. The angle \phi_{mix} is the mixing angle between left and right handed quarks., Comment: 20 pages, 9 figures

Abstract

Measurements of the trilinear gauge boson couplings WWgamma 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 Delta(g_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 lambda_gamma, the WWgamma 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 jjlv, 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., Comment: 20 pages, 4 figures, Accepted by Phys. Lett. B

Abstract

Searches for spontaneous R-parity violating signals at sqrt(s) = 183 GeV and sqrt(s) = 189 GeV have been performed using the 1997 and 1998 DELPHI data, under the assumption of R-parity breaking in the third lepton family. The expected topology for the decay of a pair of charginos into two acoplanar taus plus missing energy was investigated and no evidence for a signal was found. The results were used to derive a limit on the chargino mass and to constrain the allowed domains of the MSSM parameter space., 18 pages, 6 figures, Accepted by Physics Letters B

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

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

A study of $b$ semileptonic decays into $D$, $D\pi^{\pm}$ and $D^*\pi^{\pm}$ final states is presented.The $D^0$, $D^+$ and $D^{*+}$ mesons are exclusively reconstructed in $Z$ decay data recorded from 1992 to 1995in the DELPHI experiment at LEP. The overall branching fractions are measured to be: $BR(b -> D^0 \ell^- \bar{\nu}_{\ell} X) = (7.04 +/- 0.34 (stat) +/- 0.36 (syst.exp) +/- 0.17 (BR_D))\%,$ $BR(b -> D^+ \ell^- \bar{\nu}_{\ell} X) = (2.72 +/- 0.19 (stat) +/- 0.16 (syst.exp) +/- 0.18 (BR_D))\%$, $BR(b -> D^{*+} \ell^- \bar{\nu}_{\ell} X) = (2.75 +/- 0.17 (stat) +/- 0.13 (syst.exp) +/- 0.09 (BR_D))\%$ where the $D^0$ and $D^+$ results include also contributions from $D^{*0}$ and $D^{*+}$ decays. A study of $b$ semileptonic decays into $D$, $D\pi^{\pm}$ and $D^*\pi^{\pm}$ final states is presented.The $D^0$, $D^+$ and $D^{*+}$ mesons are exclusively reconstructed in $Z$ decay data recorded from 1992 to 1995in the DELPHI experiment at LEP.

A study of b semileptonic decays into D, D pi+- and D* pi+- 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 -> D^0 \ell^- \bar{\nu}_{\ell} X) = (7.04 +/- 0.34 (stat) +/- 0.36 (syst.exp) +/- 0.17 (BR_D))% BR(b -> D^+ \ell^- \bar{\nu}_{\ell} X) = (2.72 +/- 0.19 (stat) +/- 0.16 (syst.exp) +/- 0.18 (BR_D))% BR(b -> D^{*+} \ell^- \bar{\nu}_{\ell} X) = (2.75 +/- 0.17 (stat) +/- 0.13 (syst.exp) +/- 0.09 (BR_D))% where the D0 and D+ results include also contributions from D*0 and D*+ decays. A fit to the distribution of the pi+- impact parameter to the primary interaction vertex provides a measurement of the b semileptonic branching fractions into the D0 pi+- X, D+ pi+- X and D*+ pi+- X final states. Assuming that single pion decay modes of B mesons dominate, the partial rates for \bar{B} -> D \pi \ell^- \bar{\nu_{\ell}} and \bar{B} -> D^{*} \pi \ell^- \bar{\nu_{\ell}} have been obtained, corresponding to a total branching fraction: BR(\bar{B} -> D \pi \ell^- \bar{\nu_{\ell}}) + BR(\bar{B} -> D^{*} \pi \ell^- \bar{\nu_{\ell}}) = (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 \bar{B} -> D \ell^- \bar{\nu_{\ell}} and D^* \ell^- \bar{\nu_{\ell}} branching fractions.

Abstract

A search for the supersymmetric partner of the goldstino, the sgoldstino S, at LEP2 is presented. The production Sgamma followed by S decay into two gluons or into two photons was studied at 189 - 202 GeV LEP centre-of-mass energies. No evidence for the S production was found and limits on the S mass corresponding to different theory parameters are given., 15 pages, 7 figures

Abstract

Searches for pair production of supersymmetric particles in e$^{+}$e$^{-}$ collisions at centre-of-mass energy of 183~GeV have been performed on DELPHI data under the assumption that $R$-parity is not conserved. Only one $R$-parity violating coupling of $\lambda$ type, which couples the sleptons to the leptons ($LL \bar{E}$ term), is considered to be dominant at a time. Since in models with $R$-parity violation any supersymmetric particle can be the lightest one, searches for charginos, neutralinos, sleptons and squarks have been performed both for direct $R$-parity violating decays and for indirect cascade decays. Morever, it is assumed that the strength of the $R$-parity violating couplings is such that the lifetimes can be neglected. The present study of supersymmetric particle pair production is used to exclude domains of the Minimal Supersymmetric Standard Model parameter space previously explored under the assumption of $R$-parity conservation.

Abstract

A measurement of the forward--backward asymmetry of $e^{+}e^{-} \to c\bar{c}$ and $e^{+}e^{-} \to b\bar{b}$ on the $Z$ resonance is performed using about 3.5 million hadronic $Z$ decays collected by the DELPHI detector at LEP in the years 1992 to 1995. The heavy quark is tagged by the exclusive reconstruction of several $D$ meson decay modes. The forward--backward asymmetries for $c$ and $b$ quarks at the $Z$ resonance are determined to be: \[ \renewcommand{\arraystretch}{1.6} \begin{array}{rcr@{\!\!\;\,}l} \Afbc(\sqrt{s} = 91.235 \, {\rm GeV}) &=& &0.0659\,\, \pm\,\, 0.0094\, (stat)\,\, \pm\,\, 0.0035\, (syst) \\ \Afbb (\sqrt{s} = 91.235 \, {\rm GeV}) &=& &0.0762\,\, \pm\,\, 0.0194\, (stat)\,\, \pm\,\, 0.0085\, (syst) \\ \Afbc(\sqrt{s} = 89.434\, {\rm GeV}) &=&-&0.0496\,\, \pm\,\, 0.0368\, (stat)\,\, \pm\,\, 0.0053\, (syst) \\ \Afbb(\sqrt{s} = 89.434\, {\rm GeV}) &=& &0.0567\,\, \pm\,\, 0.0756\, (stat)\,\, \pm\,\ 0.0117\, (syst) \\ \Afbc(\sqrt{s} = 92.990\, {\rm GeV}) &=& &0.1180\,\, \pm\,\, 0.0318\, (stat)\,\, \pm\,\, 0.0062\, (syst) \\ \Afbb(\sqrt{s} = 92.990\, {\rm GeV}) &=& &0.0882\,\, \pm\,\, 0.0633\, (stat)\,\, \pm\,\, 0.0122\, (syst) \\ \end{array} \] The combination of these results leads to an effective electroweak mixing angle of: A measurement of the forward--backward asymmetry of $e^{+}e^{-} \to c\bar{c}$ and $e^{+}e^{-} \to b\bar{b}$ on the $Z$ resonance is performed using about 3.5 million hadronic $Z$ decays collected by the DELPHI detector at LEP in the years 1992 to 1995.

Abstract

A search for the Higgs boson in final states with one, two or three isolated photons has been performed based on data taken at LEP 2 by the DELPHI detector. The data analysed correspond to a total integrated luminosity of 67.5 pb −1 at centre-of-mass energies of 161 GeV (9.7 pb −1 ), 172 GeV (10.1 pb −1 ) and 183 GeV (47.7 pb −1 ). No evidence for the processes e + e − → Hγ with H→b b ̄ or γγ and e + e − →Hq q ̄ with H → γγ was observed. Model-independent limits on σ(e + e − →Hγ)×BR(H→b b ̄ ) , σ(e + e − →Hq q ̄ )×BR(H→γγ) and σ ( e + e − → Hγ )× BR ( H → γγ ) are set, as well as model-dependent limits on Higgs boson anomalous couplings to vector bosons.

Abstract

Promptly decaying lightest neutralinos and long-lived staus are searched for in the context of light gravitino scenarios. It is assumed that the stau is the next to lightest supersymmetric particle (NLSP) and that the lightest neutralino is the next to NLSP (NNLSP). Data collected with the Delphi detector at centre-of-mass energies from 161 to 183~\GeV\ are analysed. No evidence of the production of these particles is found. Hence, lower mass limits for both kinds of particles are set at 95\% C.L.. The mass of gaugino-like neutralinos is found to be greater than 71.5 GeV/$c^2$. In the search for long-lived stau, masses less than 70.0 to 77.5~\GeVcc\ are excluded for gravitino masses from 10 to 150~\eVcc . Combining this search with the searches for stable heavy leptons and Minimal Supersymmetric Standard Model staus a lower limit of 68.5~\GeVcc\ may be set for the stau mass Promptly decaying lightest neutralinos and long-lived staus are searched for in the context of light gravitino scenarios.

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

The ratios of cross sections, Rb = a(e+e- → bb)/a(e+e- → hadrons) and R, = cr(e+e- → E)/a(e+e- → hadrons) and , and the forward-backward asymmetries and , have been measured by the four LEP experiments at centre-of-mass energies close to the Z boson mass, using a variety of heavy flavour identification techniques and analysis methods. The procedure adopted to combine these measurements is described here. It takes into account the statistical and systematic correlations among the measurements and their interdependences in a χ2 minimization. The procedure is illustrated using published measurements., Facultad de Ciencias Exactas

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

During the last 1995 data acquisition period at LEP, the DELPHI experiment collected an integrated luminosity of $5.9$ pb$^{-1}$ at centre-of-mass energies of 130 GeV and 136 GeV. Radiative leptonic events ($e, \mu, \tau$) with high energy photons were studied and compared to Standard Model predictions. The data were used to search for charged excited leptons decaying through an electromagnetic transition. No significant signal was found. From the search for pair produced excited leptons, the limits $m_{e^*} > 62.5$ GeV/$c^2$, $m_{\mu^*} > 62.6$ GeV/$c^2$ and $m_{\tau^*} > 62.2$ GeV/$c^2$ at 95\% confidence level were established. For single excited lepton production, upper limits on the ratio $\lambda/m_{\ell^*}$ of the coupling of the excited charged lepton to its mass were derived.

Abstract

Muon pair production in the process $e^+e^-\to e^+e^-\mu^+\mu^-$ is studied using the data taken at LEP1 ($\sqrt{s}\simeq m_Z$) 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 $Q^2$ range accessible at LEP1 (from several GeV$^2/c^4$ to several hundred GeV$^2/c^4$) 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 $F_2^\gamma$. Azimuthal correlations are used to obtain information on additional structure functions, $F_A^\gamma$ and $F_B^\gamma$, which originate from interference terms of the scattering amplitudes. The measured ratios $F_A^\gamma/F_2^\gamma$ and $F_B^\gamma/F_2^\gamma$ are significantly different from zero and consistent with QED predictions.
