Progress in the Evaluation of the \overline B \to Xs \gamma Decay Rate at NNLO

T. Schutzmeier

The theoretical status of NNLO QCD corrections to the inclusive radiative \overline B \to Xs \gamma decay in the standard model is briefly overviewed. Emphasis is put on recent results for three-loop fermionic corrections to matrix elements of the most relevant four-quark operators.
