Abstract

We derive a new factorization relation for the semileptonic radiative decay B→π νγ in the kinematical region of a slow pion |p→π|∼Λ and an energetic photon Eγ Λ, working at leading order in Λ/mb. In the limit of a soft pion, the nonperturbative matrix element appearing in this relation can be computed using chiral perturbation theory. We present a phenomenological study of this decay, which may be important for a precise determination of the exclusive nonradiative decay.
