Radiative Leptonic $B_c$ Decays

Abstract

We analyze the radiative leptonic $B_c$ decay mode: $B_c\to \ell \nu \gamma$ ($\ell =e,\mu$) using a QCD-inspired constituent quark model. The prediction: $\mathcal{B}(B_c\to \ell \nu \gamma )\simeq 3\times 10^{-5}$ makes this channel experimentally promising in view of the large number of $B_c$ mesons which are expected to be produced at the future hadron facilities.
