摘要：

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