QCD Calculations of Radiative B Decays

Mikolaj Misiak

Published 2008-08-22, updated 2009-03-05Version 2

The current status of B -> Xs gamma decay rate calculations is summarized. Missing ingredients at the NNLO level are listed. The global normalization factor and non-perturbative effects are discussed. Arguments are presented that results for the cutoff-enhanced perturbative corrections have been misused in Ref. [15] by applying them in the region E_gamma \in [1.0, 1.6] GeV, which means that the corresponding numerical effect on BR(B -> Xs gamma, E_gamma > 1.6 GeV) is unreliable.
