Developments in the evaluation of m_c dependent matrix elements in B -> Xs gamma at NNLO

Abstract

The full prediction of the inclusive radiative B -> Xs gamma decay rate at NNLO requires a complete evaluation of missing charm quark mass dependent matrix elements. Recent developments in the on-going computations are reported and the current status is briefly overviewed.
