摘要：

Noting the absence of a complete calculation of the charged-Higgs-boson induced penguin diagram in the literature, we present an exact calculation of the vertex sbgBAR in the context of the two-Higgs-doublet model. In particular, all external masses are included, although we take no account of initial- and final-state QCD interactions. We use an on-shell renormalization scheme for the fermion "self-energy" diagrams, and use the Ward-Takahashi identity for the three-point diagram.
