Abstract

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