The O(alphaem/alphas) correction to BR[B -> Xs gamma]
Abstract
We evaluate the O(alphaem/alphas) correction to the rate of B -> Xs gamma decay, i.e. we resum all the 0[ alphaem ln MW2/mb2 x (alphas ln MW2/mb2)n ] corrections for n=0,1,2,... Our calculation differs from the previously available one by that it takes into account the complete relevant set of operators. The correction is found to be negligible, i.e. it is below 1%, in accordance with the former results.
