Abstract

I discuss the renormalization-group equation governing the leading order light-cone distribution amplitude of the B-meson phiB+(omega,mu) and its exact analytic solution. The solution displays two features concerning the asymptotic behaviour of phiB+(omega,mu) for small and large values of omega. I comment on further applications and argue that the loss of normalizability is not a problem in practice.
