Abstract:

The measurement of B0 lifetime with partially reconstructed B0→D-ℓ+νℓ decay was presented. The statistical error of the validation was included in the background systematic error. Results showed that the final relative error of ±1.9% was found by adding in quadrature the uncertainties from the sources.

Abstract:

This biennial Review summarizes much of Particle Physics. Using data from previous editions, plus 2205 new measurements from 667 papers, we list, evaluate, and average measured properties of gauge bosons, leptons, quarks, mesons, and baryons. We also summarize searches for hypothetical particles such as Higgs bosons, heavy neutrinos, and supersymmetric particles. All the particle properties and search limits are listed in Summary Tables. We also give numerous tables, figures, formulae, and reviews of topics such as the Standard Model, particle detectors, probability, and statistics. This edition features expanded coverage of CP violation in B mesons and of neutrino oscillations. For the first time we cover searches for evidence of extra dimensions (both in the particle listings and in a new review). Another new review is on Grand Unified Theories. A booklet is available containing the Summary Tables and abbreviated versions of some of the other sections of this full Review. All tables, listings, and reviews (and errata) are also available on the Particle Data Group website: http://pdg.lbl.gov.

Abstract:

The results from a search for the flavor-changing neutral current decays were presented. The data sample was collected with the BABAR detector at PEP-II B factory. The signal efficiency of the decays were determined from phase-space Monte Carlo simulations. The Bele central value of 90% C.L. was obtained and was found close to standard model predictions for these branching fractions.

Abstract:

The results of a search for T and CP violation in B0-µþÌ„0 mixing were presented. A same-sign dilepton asymmetry was obtained which was used to to extract the modulus of the ratio of complex mixing parameters. The background dilution correction was measured using data from full dilepton sample. The uncertainity on the ratio resulted in a ±3% multiplicative error.

Abstract:

A new technique involving the time-difference distribution of a tagged sample of fully reconstructed neutral B decays was used to determine the B0-µþÌ„0 mixing frequency Δmd. The obtained result is consistent with the current world average and a recent BABAR measurement with a dilepton sample.
