Next-to-Leading QCD Corrections to B \to X_{s}\gamma: Standard Model and Two-Higgs Doublet Model

We present the QCD corrections to the matching conditions of the Delta B =1 magnetic and chromo-magnetic operators in the Standard Model and in two-Higgs doublet models. We use an off-shell matching procedure which allows us to perform the computation using Taylor series in the external momenta, ins...
