چکیده

We report a measurement of the Bs(0) lifetime in the semileptonic decay channel Bs(0) --> Ds- mu+ nuX (and its charge conjugate), using approximately 0.4 fb(-1) of data collected with the D0 detector during 2002-2004. Using 5176 reconstructed Ds- mu+ signal events, we have measured the Bs(0) lifetime to be tau(Bs(0))=1.398+/-0.044(stat)(-0.025)(+0.028)(syst) ps. This is the most precise measurement of the Bs(0) lifetime to date.

Measurements of B hadron lifetimes at CDF

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 a...

Time Dependent B 0 ¯ B 0 Mixing at CDF

Measurements of the frequencies for Bd and Bs mesons to oscillate into B̄d and B̄s, respectively, can potentially constrain the magnitudes of the CKM matrix elements Vts and Vtd. These frequencies are proportional to ∆md and ∆ms, the mass differences between the CP eigenstates of the Bd and Bs mesons. Recent measurements have provided precise determinations of ∆md and lower limits on ∆ms . The la...

the DELPHI detector at LEP.

Study of spectral moments in semileptonic decays of the b hadron with the DELPHI detector at LEP. The measurement of the moments of hadronic mass spectrum and of lepton energy spectrum based on a sample of semileptonic decays of the b hadron selected from Z 0 → b ¯ b events recorded with the Delphi detector at LEP, are presented. These results are interpreted in terms of constraints on the quar...

DØnote 4376 Measurement of Lifetime Ratio for Neutral and Charged B Mesons

The measurement of the lifetime ratio for neutral and charged B mesons was performed using the statistics collected by DØ experiment in Run II and corresponding to approximately 250 pb−1. B hadrons were reconstructed in semileptonic decays B → μ+νD∗(2010)−X, which are dominated by B decays and B → μνDX, which are dominated by B decays. The lifetime ratio was obtained from the variation of the r...

CP-conserving and CP-violating properties in semileptonic Bs decays with the DØ experiment

A search for CP violation has been performed in a sample of semileptonic Bs decays corresponding to approximately 5 fb−1 of data collected by the DØ detector in Run II at the Fermilab Tevatron collider. A time-dependent fit to the distributions of Bs candidates yields the flavour-specific asymmetry af s = [−1.7±9.1(stat) +1.2 −2.3(syst)]×10 −3, corresponding to the most precise measurement to d...
