dc.descriptionWe 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 $Ψ_A-Ψ_V$ and confirm constraints on $ϕ_+$ and $ϕ_-$ derived from the light-quark equation of motion.
