Factorization and Sudakov resummation in leptonic radiative B decay — a reappraisal

Abstract The B-meson light-cone distribution amplitude is an important non- perturbative quantity arising in the factorization of the amplitudes for many exclusive decays of B mesons, such as B − → γℓ − ν ¯ $$ \overline{\nu} $$ . We reconsider the renormalization-group (RG) equation satisfied by thi...
