Leptonic Constant from B Meson Radiative Decay
arXiv:hep-ph/9506332 · doi:10.1016/0370-2693(96)00079-2
Abstract
We propose a method to determine the leptonic decay constant $f_{B^*}$ in the infinite heavy quark mass limit from the analysis of the radiative decay mode $B^- \to \ell^- {\bar ν}_\ell γ$. The method relies on HQET symmetries and on experimental data from $D^{*0} \to D^0 γ$.
