NNLO QCD corrections to the m_c dependent matrix elements in B -> X_s gamma
Abstract
Description
Recent developements in the calculation of the NNLO QCD corrections to the charm quark mass dependent matrix elements in B -> X_s gamma are reported. Special emphasis is put on the new results of the virtual O(alpha_s^2) fermionic contribution to these matrix elements [1].
