On the Decay Mode $B^{-}\to {\mu }^{-}{\bar{\nu }}_{\mu }\gamma$

Abstract

A QCD relativistic potential model is employed to compute the decay rate and the photon spectrum of the process $B^{-}\to {\mu }^{-}{\bar{\nu }}_{\mu }\gamma$. The result $\mathcal{B}(B^{-}\to {\mu }^{-}{\bar{\nu }}_{\mu }\gamma )\simeq 1\times 10^{-6}$ 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 $V_{ub}$.
