High Energy Physics - Phenomenology 2015-06-18 v1 High Energy Physics - Experiment

Abstract

We compute the O(αs)O(\alpha_s) corrections to the Wilson coefficient of the chromomagnetic operator in inclusive semileptonic B decays. The results are employed to evaluate the complete O(αsΛ2/mb2)O(\alpha_s \Lambda^2/m_b^2) correction to the semileptonic width and to the first moments of the lepton energy distribution.
