Lifetime difference of B(s) mesons: Theory status

Beneke, Martin; Lenz, Alexander

Abstract

We give an update on the lifetime difference of Bs mesons which accounts for recent lattice bag parameter results, and obtain (ΔΓ/Γ)Bs = (9.3+3.4-4.6)%. We then review the current theoretical uncertainties and conclude with a pessimistic perspective on further improvements.
