Resummed Transverse Momentum Distribution in b->s+gamma
Abstract
Description
We present the complete calculation of the transverse momentum distribution for the decay b-> s gamma. The contributions of the leading operator O_7 are computed: infrared logarithms are resummed with next-to-leading accuracy according to usual techniques of resummation. Non logarithmic terms are evaluated to O(alpha_S) by calculating one loop diagrams.
