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(B0d) and τ(B-)/τ(B0d) and the lifetime difference, ΔΓBs / ΓBs, in the neutral Bs meson system.
