    Search for anomalous production of di-lepton events with missing transverse momentum in e<sup>+</sup>e<sup>-</sup> collisions at √S = 161 and 172 GeV

    , European Physical Journal C, Vol: 4, Pages: 47-74, ISSN: 1434-6044

    Events containing two charged leptons and significant missing transverse momentum are selected from a data sample corresponding to a total integrated luminosity of 20.6 pb-1 at centre-of-mass energies of 161 GeV and 172 GeV. The observed number of events, four at 161 GeV and nine at 172 GeV, is consistent with the number expected from Standard Model processes, predominantly arising from W+W-1 production with each W decaying leptonically. This topology is also an experimental signature for the pair production of new particles that decay to a charged lepton accompanied by one or more invisible particles Further event selection criteria are described that optimise the sensitivity to particular new physics channels No evidence for new phenomena is observed and limits on the production of scalar charged lepton pairs and other new particles are presented.

    K<sup>0</sup><inf>S</inf> production in τ decays

    , European Physical Journal C, Vol: 4, Pages: 29-45, ISSN: 1434-6044

    From a sample of about 160k Z → τ+τ- candidates collected with the ALEPH detector at LEP between 1991 and 1995, τ lepton decays involving K0S → π+π- are studied. The K0SK0L associated production in τ decays is also investigated. The branching ratios are measured for the inclusive decay B(τ-→K0SX-ν τ) = (9.70±0.58±0.62) × 10-3, where X- can be anything, and for the exclusive decays B(τ-→K̄0π-ν τ) = (8.55±1.17±0.66) × 10-3, B(τ-→K̄0π-π 0ντ) = (2.94±0.73±0.37) × 10-3, B(τ-→K̄0K-ντ) = (1.58±0.42±0.17) × 10-3, B(τ-→K̄0K-π 0ντ) = (1.52±0.76±0.21) × 10-3. The decay τ-→K0SK0Lπ-ντ is studied for the first time, giving a branching ratio B(τ-→K0SK0Lπ-ντ) = (1.01±0.23±0.13) × 10-3. The channels τ- → K0SK0Sπ-ν τ , τ- → K0SK0Sπ-π 0ντ , τ- → K0SK0Lπ-π 0ντ , τ- → K̄0π-π0π0ν τ, τ-→K0K-π0π 0ντ and τ-→K0h+h-h -ντ are also investigated. In addition, mass spectra in the K0Sh- and K0Sh-π0 final states are analysed to provide information on the intermediate states produced in the decays.

    Construction and performance of the new ALEPH vertex detector

    , Nuclear Physics B - Proceedings Supplements, Vol: 61, Pages: 201-206, ISSN: 0920-5632

    A new Silicon Vertex Detector was developed for the ALEPH experiment and first installed for the high energy run at 130 GeV at the end of 1995. The detector has an active length of 40 cm and consists of two concentric layers of silicon wafers with double-sided readout. It extends the angular coverage, has only half the passive material as the former detector in the tracking volume and is radiation hard to cope with the higher level of radiation background expected for the LEP2 phase. The construction and the performance of the detector is described.

    An upper limit for the τ-neutrino mass from τ → 5π<sup>±</sup>v<inf>τ</inf> decays

    , European Physical Journal C, Vol: 5, Pages: 229-237, ISSN: 1434-6044

    An upper limit for the τ-neutrino mass has been determined from the decay τ → 5π±vτ using data collected with the OPAL detector from 1991 to 1995 in e+e- collisions at √s ≈ Mz. A limit of 43.2 MeV at 95% CL is obtained using a two-dimensional method in the 5π invariant mass and energy distribution from 22 selected events. Combining this result with OPAL's previously published measurement using τ+ τ- → 3h±v̄τ + 3h∓vτ decays, a new combined limit of mvτ < 27.6 MeV (95% CL) is obtained.

    Investigation of CP violation in B<sup>0</sup> → J/ψK<inf>S</inf><sup>0</sup> decays at LEP

    , European Physical Journal C, Vol: 5, Pages: 379-388, ISSN: 1434-6044

    An investigation of CP violation was performed using a total of 24 candidates for B0 → J/ψK0S decay, with a purity of about 60%. These events were selected from 4.4 million hadronic Z0 decays recorded by the OPAL detector at LEP. An analysis procedure, involving techniques to reconstruct the proper decay times and tag the produced b-flavours, B0 or B̄0, has been developed to allow a first direct study of the time dependent CP asymmetry that, in the Standard Model, is sin 2β. The result is sin 2β = 3.2+1.8-2.0 ± 0.5 where the first error is statistical and the second systematic. This result is used to determine probabilities for different values of sin 2β in the physical region from -1 to +1.

    Study of bialkali photocathodes below room temperature in the uv/vuv region

    , IEEE Transactions on Nuclear Science, Vol: 45, Pages: 542-549, ISSN: 0018-9499

    Two photomultiplier tubes with bialkali photocathodes and fused silica windows (2″ Philips XP2020Q and 1-1/8" Hamamatsu R1668) were studied between room temperature and -160°C, illuminated in dc mode in the UV/VUV wavelength range. The photomultipliers were operated as diodes, with direct measurement of the current of photoelectrons, in order to study in detail the effects associated to the photocathode. The influence of light intensity, applied voltage and illuminated area on the response as a function of temperature were investigated. The increase of the electrical resistivity of the emissive layer upon cooling proved to be responsible for a loss of linearity of the photocathode response, leading ultimately to the complete absence of signal at low temperature. A simplified model is presented that accounts for some experimental results. An unexpected increase of response below room temperature was also found at 170 nm. © 1998 IEEE.

    Measurement of the B<sup>0</sup><inf>d</inf> - B̄<sup>0</sup><inf>d</inf> oscillation frequency

    , European Physical Journal C, Vol: 5, Pages: 195-203, ISSN: 1434-6044

    Time-dependent B0-B̄0 mixing is studied using about two million hadronic Z decays registered by L3 in 1994 and 1995. For this study three techniques are used. Tagging of the b-quark charge at decay time is performed by identifying leptons from semileptonic B decays. The flavour of the b quark at production time is determined from the charge of the lepton in the opposite hemisphere or by using a jet-charge technique. The proper time of the B-particle decay is obtained by reconstructing the production and decay vertices or by a measurement of the lepton impact parameter. The combined result for the frequency of B0d meson oscillations is Δmd = 0.444 ± 0.040 ps-1.

    Studies of quantum chromodynamics with the ALEPH detector

    , Physics Report, Vol: 294, Pages: 1-165, ISSN: 0370-1573

    Previously published and as yet unpublished QCD results obtained with the ALEPH detector at LEP1 are presented. The unprecedented statistics allows detailed studies of both perturbative and non-perturbative aspects of strong interactions to be carried out using hadronic Z and tau decays. The studies presented include precise determinations of the strong coupling constant, tests of its flavour independence, tests of the SU(3) gauge structure of QCD, study of coherence effects, and measurements of single-particle inclusive distributions and two-particle correlations for many identified baryons and mesons. © 1998 Elsevier Science B.V.

    π<sup>±</sup>, K<sup>±</sup>, p and p̄ production in Z<sup>0</sup> → qq̄, Z<sup>0</sup> bb̄, Z<sup>0</sup> → uū, dd̄, ss̄

    , European Physical Journal C, Vol: 5, Pages: 585-620, ISSN: 1434-6044

    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 protons, covering the full momentum range from 0.7 < p < 45.6GeV/c. The π±, K±, p and p̄ normalised production rates, their differential cross sections, multiplicities and the maxima ξ*p of_the ξp = ln (1/Xp) distributions are measured for three event samples Z0 → qq̄, Z0 → bb̄, Z0 → uū, dd̄, ss̄, selected from ∼ 1 400 000 Z0 decays 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 Approximation with Local Parton-Hadron Duality is tested. The ξ*p dependence on the primary quark flavour is investigated and quantified for the different particle distributions. The π± , K±, p and p̄ multiplicities are measured with precisions from ±4% to ±6%. Forche Z0 → qq̄, and Z0 → bb̄, event samples, these improve on previous measurements. The π±, K±, p and p̄ multiplicities for Z0 → uū, dd̄, ss̄ are presented for the first time.

    A measurement of the B<sup>0</sup><inf>s</inf> lifetime using reconstructed D<sup>-</sup><inf>s</inf> mesons

    , European Physical Journal C, Vol: 2, Pages: 407-416, ISSN: 1434-6044

    We report a measurement of the B0s meson lifetime from B0s → D-sX decays, where D-s mesons are reconstructed in the D-s → φπ- and D-s → K*0K- decay channels. From approximately 3.7 million hadronic Z0 decays recorded by the OPAL detector at LEP a sample is selected containing 911 ± 83 candidates, of which 519 ± 136 are estimated to be from B0s meson decays. Fitting the distribution of the distance from the beam spot to the decay vertex of the D-s candidates with an unbinned likelihood function we measure π(B0s) = 1 72+0.20+0.18-0.19-0.17 ps, where the errors are statistical and systematic, respectively.
