Recent progress on the nonlocal power corrections to the inclusive penguin decays B Xs γ and B Xs
Abstract
We report on recent progress in the field of nonlocal (so-called resolved) contributions to the inclusive penguin decays which presently belong to the largest uncertainties in these inclusive decay modes. There is still a very large scale and a large charm mass dependence in the present leading order results which can in the future be decreased by including the αs corrections.
