Bs Decays and Mixing

Bs, Bc and b-baryons

We present the latest measurements on masses, lifetimes and branching fractions for the Bs and Bc mesons as well as for b-baryons. For the Bs meson we discuss as well the latest results on mixing. These results were produced by the CDF and D0 experiments at Fermilab or by earlier LEP and PEPII experiments.

Bs−Bs mixing with a chiral light quark action

We study the B 0 s − B 0 s mixing amplitude in Standard Model by computing the relevant hadronic matrix element in the static limit of lattice HQET with the Neuberger light quark action. In the quenched approximation, and after matching to the MS scheme in QCD, we obtain B MS B s (m b) = 0.940(16)(22). c Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCom...

Extracting CKM Phases and Bs–Bs Mixing Parameters from Angular Distributions of Non-Leptonic B Decays

Suggestions for efficiently determining the lifetimes and mass difference of the light and heavy Bs mesons (B L s , B H s ) from Bs → J/ψφ,D∗+ s D∗− s decays are given. Using appropriate weighting functions for the angular distributions of the decay products (moment analysis), one can extract (ΓH ,ΓL,∆m)Bs . Such a moment analysis allows the determination of the relative magnitudes and phases o...
