英文摘要: In the "Higgs basis" for a generic 2HDM, only one scalar doublet gets a nonzero vacuum expectation value and, under the criterion of minimal flavor violation, the other one is fixed to be either color-singlet or color-octet, which are named as the type-III and type-C models, respectively. In this paper, the charged-Higgs effects of these two models on B-s(0)-(B) over bar (0)(s) mixing are studied. First of all, we perform a complete one-loop computation of the electro-weak corrections to the amplitudes of B-s(0)-(B) over bar (0)(s) mixing. Together with the up-to-date experimental measurements, a detailed phenomenological analysis is then performed in the cases of both real and complex Yukawa couplings of charged scalars to quarks. The spaces of model parameters allowed by the current experimental data on B-s(0)-(B) over bar (0)(s) mixing are obtained and the differences between type-III and type-C models are investigated, which is helpful to distinguish between these two models.
