Width difference of the Bs mesons from lattice QCD
We extend our previous studies to calculate the B meson B parameters BB and BS on the lattice, and present an update of the results for the Bs meson width difference. We perform an extensive study of systematic errors in the quenched calculation of the B-parameters, and find that the systematic errors are in good control using the NRQCD action for heavy quark. We also report our preliminary res...
متن کاملStudies of CP-conserving and CP-violating Bs mixing parameters with the D0 experiment
This paper summarises the recent results of the Run IIa D0 experiment at the Tevatron Collider at Fermilab on the observable parameters of the Bs meson. A measurement of the branching fraction Br(B s → D (∗) s D (∗) s ) is reported, which provides an estimate of the width difference ∆Γ s /∆Γs. Through the decay Bs → J/ψφ the width difference ∆Γs is extracted, and for the first time a constraint...
متن کاملExploiting the width difference in B s → φγ
The photon polarization in B → V γ is a sensitive probe of right-handed currents. In the time dependent decay rate of Bs → φγ the coefficients S and H in front of the sin(∆mst) and the sinh(∆Γs/2t) terms are sensitive to those right-handed currents. As compared to the Bd system there is a sizable width difference in Bs mesons which leads to the additional measurable observable H . We show with ...
متن کاملLifetime Difference of B S Mesons and Its Implications A
We discuss the calculation of the width difference ∆Γ Bs between the Bs mass eigen-states to next-to-leading order in the heavy quark expansion. 1/m b-corrections are estimated to reduce the leading order result by typically 30%. The error of the present estimate (∆Γ/Γ) Bs = 0.16 +0.11 −0.09 could be substantially improved by pinning down the value of ¯ Bs|(¯ b i s i) S−P (¯ b j s j) S−P |Bs an...
متن کاملWidth difference in the Bs-B̄s system with lattice nonrelativistic QCD
We present a lattice calculation of the Bs-B̄s transition-matrix element through a four-quark operator OS 5 b̄(12g5)sb̄(12g5)s , which gives a leading contribution in the calculation of the width difference DGs in the 1/mb expansion. The nonrelativistic QCD formulation is used to describe b quark on the lattice. Using the next-to-leading formula of Beneke et al., we obtain (DG/G)s50.151(37)(45)(17...
