Bremsstrahlung corrections to the decay {ital b}{r_arrow}{ital s}{gamma}
- Physik-Department, Technische Universitaet Muenchen, D-85747 Garching (Germany)
We calculate the {ital O}({alpha}{sub {ital s}}) gluon bremsstrahlung corrections to the inclusive decay {ital b}{r_arrow}{ital s}{gamma}, involving the full operator basis {cflx {ital O}}{sub 1}{endash}{cflx {ital O}}{sub 8}. 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. {copyright} {ital 1996 The American Physical Society.}
