Beneke, Martin and Lenz, Alexander (2001) 'Lifetime difference of B(s) mesons : theory status.', Journal of physics G : nuclear and particle physics., 27 (6). pp. 1219-1224.
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.
