B-B Mixing and b Hadron Lifetimes from Lattice QCD
Jonathan Flynn, C. -J. David Lin
Abstract
We discuss neutral Bs,d meson mixing and b-hadron lifetimes from the perspective of recent lattice calculations. In particular, we consider matrix elements which can be combined with measured ΔMs,d to constrain |Vtd|, the lifetime ratios τ(Λb)/τ(Bd) and τ(B-)/τ(Bd) and the lifetime difference, ΔΓs/Γs, in the neutral Bs meson system.
