摘要：

A QCD relativistic potential model is employed to compute the decay rate and the photon spectrum of the process B- --> <mu(-)(nu)over bar (mu)gamma>. The result B(B- --> <mu(-)(nu)over bar (mu)gamma> similar or equal to 1 x 10(-6) confirms the enhancement of this decay channel with respect to the purely leptonic mode, and supports the proposal of using this process to access relevant hadronic quantities such as the B-meson leptonic decay constant and the CKM matrix element V-ub.
