Quark mass effects in $\overline{B} \to X_{s \gamma}$ / Gambino, Paolo (CERN) ; Misiak, Mikolaj (CERN ; Warsaw U.)
The charm-loop contribution to B -> Xs gamma is found to be numerically dominant and very stable under logarithmic QCD corrections. The strong enhancement of the branching ratio by QCD logarithms is mainly due to the b-quark mass evolution in the top-quark sector. [...]
