QCD calculations of radiative heavy meson decays with subleading power corrections

Abstract We revisit QCD calculations of radiative heavy meson decay form factors by including the subleading power corrections from the twist-two photon distribution amplitude at next-to-leading-order in α s with the method of the light-cone sum rules (LCSR). The desired hard-collinear factorization...
