Abstract: Based on a sample equivalent to 365000 hadronic Z0 decays, the search in DELPHI data for pairs of leptons accompanied by a pair of charged particles is described. A total of 11 events were found in the electron channel, 9 in the muon channel and 7 in the tau channel. Results on lepton pairs with a radiated photon are also presented. The data from all channels are compatible with the expectations from standard processes. However, one event was found in the tau channel with an unusually high mass of the charged particle pair.

Abstract: From a sample of about 120 000 hadronic Z0 decays, using a technique based on a separation of the different event categories in the boosted sphericity product, the fraction of bbBAR decays has been measured to be 0.219 +/- 0.014 (stat) +/- 0.019 (syst). Using the DELPHI determination of the hadronic Z0 width, this corresponds to a partial width GAMMA(bbBAR) = 378 +/- 42 MeV (in good agreement with the standard model prediction of congruent-to 380 N eV). Combining this measurement with the determinations based on events with high p(t) leptons gives an estimate for the branching ratio of b into leptons at LEP of (11.2 +/- 1.2)%, consistent with previous determinations.

Abstract: Seven unambiguous events out of a sample of 270 000 Z0 decays, contain in tile same jet a D(s) meson and a muon at large transverse momentum relative to the et axis. These events are direct evidence for B(s)0 meson production in hadronic Z0 decays. The production rate of these events, relative to all hadronic Z0 decays is ( 18 +/- 8) x 10(-5) this number including the relevant branching fractions of the B(s)0 and D(s). The value of the B(s)0 meson lifetime relative to the average B meson lifetime is measured to be 0.8 +/- 0.4.

Abstract: A strong increase of the mean transverse momentum [p(t)] with the number of charged particles n(ch) is observed in e+e- annihilations into hadrons at LEP energies, The effect resembles correlations observed in hadron-hadron interactions. In e+e- annihilations the [p(t)] and n(ch) correlations can be accounted for by gluon radiation.

Abstract: An analysis of the fluctuations in the phase space distribution of hadrons produced in the decay of 78829 Z0 has been carried out, using the method of factorial moments. The high statistics collected by the DELPHI experiment at LEP during 1990 allowed studies of the event sample both globally and in intervals of p(t) and multiplicity, and for different jet topologies and for single jets. A large contribution to the factorial moments of the one-dimensional data on rapidity with respect to the event axis comes from hard gluons. Details of factorial moments in two and three dimensions are presented. Influences of resonance decays have been studied by Monte Carlo simulation: one-dimensional factorial moments at low p(t), and two-, three-dimensional analyses are affected. Parton shower models describe the data reasonably well.

Abstract: The study of the orientation of three-jet events from e+ e- –> Z0 –> multi-hadrons is presented, in particular the polar angle distributions of the thrust axis and of the normal to the three-jet plane, and the azimuthal correlations between the hadron plane and the one defined by the beam and thrust axes. The data are compared with results at lower energy and with QCD predictions. Good agreement with QCD predictions is observed. The scalar gluon theory is excluded by the data.

Abstract: We have searched for pair produced scalar leptoquarks each decaying to a quark and a charged lepton in a sample of 116 000 hadronic Z0 events produced at LEP. No candidate was detected and cross section and branching ratio limits are set for the above process at 95% CL. Mass limits are found to be about 42 GeV/c2 depending only slightly on the models used and a coupling times branching ratio exclusion line is drawn for a scalar leptoquark with a free coupling. We have also probed the mass region above 45 GeV/c2 for a singly produced scalar leptoquark and set limits on the cross section and the coupling lambda(2)/4-pi up to 60 GeV.

Abstract: An analysis of the production of strange particles from the decays of the Z0 boson into multihadronic final states is presented. The analysis is based on about 90 000 selected hadronic Z0 decays collected by the DELPHI detector at LEP in 1990. K(s)0, K* +/-, LAMBDA(LAMBDABAR) and XI- (XI+) have been identified by their characteristic decays. The measured production cross sections are compared with predictions of the Lund Monte Carlo tuned to data at PEP/PETRA energies.

Abstract: We have searched for possible fourth family heavy neutrinos, pair produced in Z0 decays, in a sample of about 112 000 hadronic Z0 final states collected with the DELPHI detector. For all mixing matrix elements we exclude a new Dirac neutrino lighter than 44.5 GeV at a 95% confidence level, if the neutrino couples to the electron or muon family, and lighter than 44.0 GeV, if the neutrino couples to the tau family. Depending on the values of the mixing element and to which lepton family the neutrino couples, we obtain mass limits up to 46.2 GeV. For all mixing matrix elements we exclude a new Majorana neutrino lighter than 39.0 GeV, if it couples to the electron or the muon family, and lighter than 38.2 GeV, if it couples to the tau family. Depending on the values of the mixing matrix element and to which lepton family the neutrino couples, we obtain mass limits up to 44.7 GeV. We also exclude stable new Dirac neutrinos lighter than 45.0 GeV and new Majorana neutrinos lighter than 39.5 GeV.

Abstract: The search in DELPHI data for neutral Higgs bosons is described. No candidate for the Standard Model Higgs is seen in Z0 decays to H-0-nu-nuBAR, H-0-mu+-mu- or H-0-tau+-tau- after selections that proved efficient for finding simulated H-0. One remaining candidate for Z0 –> H-0e+ e- is consistent with background. Together with our earlier studies, these results restrict the H-0 mass to be above 38 GeV/c2 at the 95% confidence level. No signal is found for decays of Minimal Supersymmetric Standard Model neutral Higgs bosons to tau+-tau-. Limits are obtained for their decays to produce four jets.

Abstract: A classifier based on a feed-forward neural network has been used for separating a sample of about 123 500 selected hadronic decays of the Z 0 , collected by DELPHI during 1991, into three classes according to the flavour of the original quark pair: u u +d d +s s (unresolved), c c and b b . The classification has been used to compute the partial widths of the Z 0 into b and c quark pairs. This gave Γ c c /Γ h = 0.151 ± 0.008 ( stat. ) ± 0.041 ( syst. ) , Γ b b /Γ h = 0.232±0.005 ( stat. )±0.017 ( syst. ) .

Abstract: View references (24)The weak mixing angle has been measured from the charge asymmetry of hadronic events with two different approaches using the DELPHI detector at LEP. Both methods are based on a momentum-weighted charge sum to determine the jet charge in both event hemispheres. In a data sample of 247 300 multihadronic Z0 decays a charge asymmetry of 〈QF〉 - 〈QB〉 = -0.0076±0.0012(stat.)±0.0005(exp. syst.)±0.0014(frag.) and a raw forward-backward asymmetry of Araw FB = -0.0109±0.0020(stat.)±0.0010(exp. syst.)±0.0017(frag.) have been measured. This result corresponds to a value of sinθeff=0.2345±0.0030(exp.)±0.0027(frag.) ,sin2θMS=0.2341±0.0030(exp.)±0. 0027(frag.) and to sin2θW=1-m2 W/m2 Z=0.2299± 0.0030(exp.)±0.0027(frag.)±0.0028(theor.). The experimental error is the quadratic sum of the statistical and the experimental systematic error and the theoretical error originates from a value of mt=130±40 GeV/c2 and a range of mH from 45 GeV/c2 to 1000 GeV/c2., 0, info:eu-repo/semantics/published

Abstract: The study of the orientation of three-jet events from e+e-→Z0→ multi-hadrons is presented, in particular the polar angle distributions of the thrust axis and of the normal to the three-jet plane, and the azimuthal correlations between the hadron plane and the one defined by the beam and thrust axes. The data are compared with results at lower energy and with QCD predictions. Good agreement with QCD predictions is observed. The scalar gluon theory is excluded by the data.

Abstract: A classifier based on a feed-forward neural network has been used for separating a sample of about 123 500 selected hadronic decays of the Z0, collected by DELPHI during 1991, into three classes according to the flavour of the original quark pair: uuBAR + ddBAR + ssBAR (unresolved), ccBAR and bbBAR. The classification has been used to compute the partial widths of the ZO into b and c quark pairs.

Abstract: Bose-Einstein correlations between pairs of like-sign charged particles produced in e+e- annihilations near the Z0 peak have been studied using data taken with the DELPHI detector at LEP. An enhancement is found in the production of pairs of identical pions of similar momenta, with respect to a reference sample. Under the hypothesis that the pions are emitted by a spherically symmetrical source with gaussian density, the data indicate a radius of the source of r = 0.62 +/- 0.04(stat.) +/- 0.20(syst.) fm. The large systematic uncertainty reflects the sensitivity of r to the choice of the reference sample.

Abstract: From measurements of the cross sections for e+ e - –> hadrons and the cross sections and forward-backward charge-asymmetries for e+ e- –> e+ e-, mu+ mu- and tau+ tau- at several centre-of-mass energies around the Z0 pole with the DELPHI apparatus, using approximately 150000 hadronic and leptonic events from 1989 and 1990, one determines the following Z0 parameters: the mass and total width M(Z) = 91.177 +/- 0.022 GeV, GAMMA(Z) = 2.465 +/- 0.020 GeV, the hadronic and leptonic partial widths GAMMA(h) = 1.726 +/- 0.019 GeV, GAMMA(t) = 83.4 +/- 0.8 MeV, the invisible width GAMMA(inv) = 488 +/- 17 MeV, the ratio of hadronic over leptonic partial widths R(Z)z = 20.70 +/- 0.29 and the Born level hadronic peak cross section sigma-0 = 41.84 +/- 0.45 nb. A flavour-independent measurement of the leptonic cross section gives very consistent results to those presented above (GAMMA(t) = 83.7 +/- 0.8 MeV). From these results the number of light neutrino species is determined to be N(nu) = 2.94 +/0. 10. The individual leptonic widths obtained are: GAMMA(e) = 82.4 +/- 1.2 MeV, GAMMA(mu) = 86.9 +/- 2.1 MeV and GAMMA(tau) = 82.7 +/- 2.4 MeV. Assuming universality, the squared vector and axial-vector couplings of the Z0 to charged leptons are: VBAR(t)2 = 0.0003 +/- 0.0010 and ABAR(l)2 = 0.2508 +/- 0.0027. These values correspond to the electroweak parameters: rho(eff) = 1.003 +/- 0.011 and sin2-theta(W)eff = 0.241 +/- 0.009. Within the Minimal Standard Model (MSM), the results can be expressed in terms of a single parameter: sin2-theta(W)MSBAR = 0.2338 +/- 0.0027. All these values are in good agreement with the predictions of the MSM. Fits yield 43 < m(top) < 215 GeV at the 95% level. Finally, the measured values of GAMMA(Z) and GAMMA(inv), are used to derive lower mass bounds for possible new particles.

Abstract: The total and differential cross-sections for the reaction e+e- –> gamma-gamma(gamma) are measured at centre of mass energies around 91 GeV using an integrated luminosity of 4.7 pb-1. The agreement with the QED prediction is good. Consequently there is no evidence for non-standard channels which would have the same experimental signature. The lower limits on the QED cutoff parameters are LAMBDA+ > 113 GeV and LAMBDA- > 95 GeV. An upper limit on the effective coupling between a possible excited electron and the gamma is derived. At 95% confidence level the branching ratios for Z0 decay into pi-0-gamma, eta-gamma and gamma-gamma-gamma are below 1.5 x 10(-4), 2.8 x 10(-4) and 1.4 x 10(-4) respectively.

Abstract: In 1996 LEP ran at a centre-of-mass energy of 161 GeV, just above the threshold of W-pair production. DELPHI accumulated data corresponding to an integrated luminosity of 9.93 pb(-1), and observed 29 events that are considered as candidates for W-pair production. From these, a cross-section for the doubly resonant e(+)e(-) –> WW process of 3.67(-0.85)(+0.97)+/-0.19 pb has been measured. Within the Standard Model, this cross-section corresponds to a mass of the W-boson of 80.40+/-0.44(stat.)+/-0.09(syst.)+/-0.03(LEP) GeV/c(2). Alternatively, if mw is held fixed at its current value determined by other experiments, the observed cross-section is used to obtain limits on trilinear WWV(V = gamma,Z) couplings.

Abstract: An inclusive measurement of the average multiplicity of b (b) over bar pairs from gluons, g(b (b) over bar), in hadronic Z(0) events collected by the DELPHI experiment at LEP, is presented. A counting technique, based on jet b-tagging in 4-jet events, has been used. Looking for secondary bottom production in events with production of any primary flavour, by requiring two b-tagged jets in well defined topological configurations, gave g(b (b) over bar) = (0.21 +/- 0.11(stat) +/- 0.09(syst))%. This result was checked with a different method designed to select events with four b quarks in the final state. Agreement within the errors was found. (C) 1997 Elsevier Science B.V.

Abstract: A study of B meson decays into DlX final states is presented. In these events, neutral and charged D mesons originate predominantly from B+ and B0 decays, respectively. The dilution of this correlation due to D** production has been taken into account. From 263 700 hadronic Z0 decays collected in 1991 with the DELPHI detector at the LEP collider, 92 D0→K-π+, 35 D+→K-π+π+ and 61 D*0→D0π+ followed by D0→K-π+ or D0→K-π+π+π -, are found with an associated lepton of the same charge as the kaon. From the D0l- and D*+l-, the probability fd that a b quark hadronizes into a B- (or {Mathematical expression}) meson is found to be 0.44 ±0.08±0.09, corresponding to a total (Bs+Λb) hadronization fraction of 0.12-0.12+0.24. By reconstructing the energy of each B meson, the b quark fragmentation is directly measured for the first time. The mean value of the B meson energy fraction is: {Mathematical expression} Reconstructing D-lepton vertices, the following B lifetimes are measured: {Mathematical expression} and an average τ(B)=1.23-0.13+0.14(stat.)±0.15(syst.) ps is found. Allowing for decays into {Mathematical expression}, the B+ and B0 lifetimes are: {Mathematical expression} © 1993 Springer-Verlag.

Abstract: A search for lepton flavour number violating Z(0) decays in the channels Z(0) –> mu tau, Z(0) –> e tau, Z(0) –> e mu, using the DELPHI detector with data collected during the 1991-94 LEP runs, is described, No signal was found. Upper limits at 95% confidence level for the respective branching fractions of 1.2 x 10(-5), 2.2 x 10(-5), and 0.25 x 10(-5), were obtained.
