Measurements of B hadron lifetimes at CDF
نویسنده
چکیده
Using data samples in excess of 1 fb collected by the CDF II detector we present several world’s best measurements of B hadron lifetimes. They include Bs meson lifetime in a flavor-specific decay mode, combining fully and partially reconstructed hadronic decays, B c meson lifetimes in semileptonic B + c → J/ψl X, l = μ, e decays and Λb baryon lifetime in Λ+c π − fully-reconstructed decays. In addition, we introduce a Monte Carlo independent technique

Recent Lifetime and Mixing Measurements at the Tevatron
We present the latest B hadron lifetimes, B s mixing, and D 0 mixing measurements using up to 3.0 fb of data collected by CDF and D0 experiments at Fermilab. The B s lifetime is measured from both J/ψφ (CP admixture) and flavor specific channels, and the Bc lifetime is obtained from semileptonic channels. Following the B s oscillation frequency measurement at CDF in 2006, the D0 collaboration n...
متن کاملFor Publisher’s use REVIEW ON B 0- B 0 MIXING AND B-LIFETIMES MEASUREMENTS AT CDF/LEP/SLD

متن کاملMeasurements of Exclusive B-hadron Lifetimes at Lep
Measurements of exclusive b-hadron lifetimes at LEP are reviewed. Each LEP experiment has collected about 3.5 million hadronic Z 0 decays between 1990 and 1994. This data allows to identify a large variety of exclusive decay chains of a speciic b hadron with suitable statistics to measure lifetimes. The world averages of exclusive b hadron lifetimes have gained a precision of less than 10%. The...
متن کاملMeasurements of b–hadron lifetimes and b–meson oscillations
In the spectator model, where the weak decay of the heavy quark is described neglecting the strong interactions with the light quark(s) in the heavy–flavoured hadron, all the hadrons containing the same heavy quark are predicted to have equal lifetimes. This model fails dramatically for charmed particles. Non–spectator effects like weak annihilation, W exchange and final state quark interferenc...
متن کاملun 1 99 5 CDF Results on B Decays
We present recent CDF results on B lifetimes, B meson mass measurements, ratios of branching ratios, and rare decays. In addition, we present the first measurement of time-dependent Bd mixing at CDF. Several results have been updated and a few new ones included since the workshop.
