摘要：

We discuss neutral B-s,B-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 DeltaM(s,d) to constrain \V-td\, the lifetime ratios tau(Lambda (b))/tau (B-d(0)) and tau (B-)/tau (B-d(0)) and the lifetime difference, Delta Gamma (Bs)/Gamma (Bs), in the neutral B-s meson system.
