We reconsider the prediction of the semileptonic branching ratio of B mesons, using the recent calculation [E. Bagan et al., Nucl. Phys. B 432 (1994) 3] of the radiative corrections with account for finite quark masses in nonleptonic decays and taking into account 1/mb2 corrections. For the semileptonic branching ratio we obtain Bsl = (11.8 ± 1.6)% using pole quark masses and Bsl = (11.0 ± 1.9) % ...
