Large-m_c Asymptotic Behaviour of O(alpha_s^2) Corrections to B -> X_s gamma

Abstract

We present details of our evaluation of the NNLO QCD corrections to BR(B -> X_s gamma) in the heavy charm limit m_c >> m_b/2. Results of this calculation have been essential for estimating O(alpha_s^2) effects in this branching ratio via interpolation in m_c.
