Renormalization of B-meson distribution amplitudes
Abstract
We summarize a recent calculation of the evolution kernels of the two-particle B-meson distribution amplitudes φ+ and φ- taking into account three-particle contributions. In addition to a few phenomenological comments, we give as a new result the evolution kernel of the combination of three-particle distribution amplitudes A-V and confirm constraints on φ+ and φ- derived from the light-quark equation of motion.
