Abstract
We briefly review the current status of the calculation of the next-to-next-to-leading-order (NNLO) QCD corrections to the branching ratio of the B → X s γ decay, and we also present the recent theoretical estimate of the latter quantity. Special attention is devoted to the study of the NNLO QCD corrections to the photon energy spectrum in the partonic process b → X s parton γ.
