Factorization of radiative leptonic decays of B− and D− mesons
In this work, we study the factorization of the radiative leptonic decays of B− and D− mesons, the contributions of the order O(ΛQCD/mQ) are taken into account. The factorization is proved to be valid explicitly at the order O(αsΛQCD/mQ). The hard kernel is obtained. The numerical results are calcul...
