摘要：

We calculate the radiative corrections to the nonleptonic inclusive B decay mode b --> cud taking into account the charm quark mass. The corrections increase the decay rate by (4-8)%, depending on the renormalization point. Using these results, we obtain an improved theoretical prediction for the semileptonic branching ratio of B mesons. This talk relies on work done in collaboration with E. Bagan, V.M. Braun and P. Gosdzinsky.
