Kinetic operator effects in B-> X_c l nu at O(alpha_s) [PDF]
Andrea Alberti, Thorsten Ewerth, Paolo Gambino, Soumitra NandiWe compute the O(alpha_s) corrections to the Wilson coefficient of the kinetic operator in inclusive semileptonic B decays. Our analytic calculation agrees with reparameterization invariance and with previous numerical results and paves the way to the calculation of analogous corrections to other power-suppressed coefficients.View original: http://arxiv.org/abs/1212.5082
