$B R (B ˉ \to X_{s} γ)$ : First Next-to-Next-to-Leading Order Results

arXiv:hep-ph/0406240 · doi:10.1016/j.nuclphysbps.2004.09.015

Abstract

In this contribution the first next-to-next-to-leading order corrections to the branching ratio $B R (B ˉ \to X_{s} γ)$ are discussed. This includes the completion of the matching part and the fermionic corrections to the most important operator matrix elements.
