Bremsstrahlung corrections to the decay $b \to s \gamma$
Abstract
We calculate the O() gluon Bremsstrahlung corrections to the inclusive decay , involving the full operator basis -- . Confirming and extending earlier calculations of Ali and Greub, we give formulas for the total decay width as well as the perturbative photon spectrum, regarding the former as a necessary part of the forthcoming complete NLO analysis. We explore in detail the renormalization scale dependence of our results and find it considerably increased.
