Weak radiative B decays

The theory of the decays B to X/sub s/ gamma and B to X/sub s/l/sup + /l/sup -/ is reviewed. The huge enhancement of the B to X/sub s/ gamma branching ratio by quantum chromodynamics logarithms is attributed to the renormalization group evolution of m/sub b/( mu ) in the top-quark contribution to th...

description The theory of the decays B to X/sub s/ gamma and B to X/sub s/l/sup + /l/sup -/ is reviewed. The huge enhancement of the B to X/sub s/ gamma branching ratio by quantum chromodynamics logarithms is attributed to the renormalization group evolution of m/sub b/( mu ) in the top-quark contribution to the decay amplitude. The residual mu dependence of the NLO predictions is discussed. (29 refs).
