The ANTARES project
NUCL PHYS B-PROC SUP 75A (1999) 415-417
Abstract:
The ANTARES project is an international collaboration with the aim of building a deep-sea large area neutrino telescope within the next decade. The achievements and status of the project as at the time of the conference are briefly discussed, and short term steps as well as longer term plans are described.Measurement of Z0 and Drell-Yan production cross sections using dimuons in p̄p collisions at √s=1.8TeV
Physical Review D - Particles, Fields, Gravitation and Cosmology 59:5 (1999) 1-15
Abstract:
We present a measurement of Z0 boson and Drell-Yan production cross sections in p̄p collisions at √s =1.8TeV using a sample of 107 pb-1 accumulated by the Collider Detector at Fermilab. The Drell-Yan cross section is measured in the mass range of Mμμ>40GeV/c2. We compare the measurements with the predictions of quantum chromodynamics in both leading order and next-to-leading order, incorporating the recent parton distribution functions. The measurements are consistent with the standard model expectations. ©1999 The American Physical Society.Measurement of the Bd 0-B̄d 0 flavor oscillation frequency and study of same side flavor tagging of B mesons in pp̄ collisions
Physical Review D - Particles, Fields, Gravitation and Cosmology 59:3 (1999) 1-41
Abstract:
Bd0-B̄d0 oscillations are observed in "self-tagged" samples of partially reconstructed B mesons decaying into a lepton and a charmed meson collected in pp̄ collisions at √s=1.8 TeV. A flavor tagging technique is employed which relies upon the correlation between the flavor of B mesons and the charge of a nearby particle. We measure the flavor oscillation frequency to be Δmd=0.471-0.068+0.078±0.034 ps-1. The tagging method is also demonstrated in exclusive samples of Bu+→J/ψK+ and Bd0→J/ψK*0(892), where similar flavor-charge correlations are observed. The tagging characteristics of the various samples are compared with each other, and with Monte Carlo simulations.Measurement of the BS 0 meson lifetime using semileptonic decays
Physical Review D - Particles, Fields, Gravitation and Cosmology 59:3 (1999) 1-14
Abstract:
The lifetime of the BS0 meson is measured using the semileptonic decay BS0→DS-l+νX. The data sample consists of about 110 pb-1 of pp̄ collisions at √s=1.8 TeV collected by the CDF detector at Fermilab. Four different DS- decay modes are reconstructed resulting in approximately 600 DS-l+ signal events. The BS0 meson lifetime is determined to be τ(BS0)=(1.36±0.09-0.05+0.06) ps, where the first and second uncertainties are statistical and systematic, respectively. The BS0 meson decay length distribution is examined for a lifetime difference ΔΓ/Γ between the two mass eigenstates of the BS0 meson. An upper limit of ΔΓ/Γ<0.83 is set at the 95% confidence level.Event-building and PC farm based Level-3 trigger at the CDF experiment
