Perturbative corrections to power suppressed effects in semileptonic B decays

Abstract

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