摘要：

The decay B --> X(sgamma) is analysed with the non-standard physical effects due to the charged Higgs contribution in the two-Higgs-doublet model. The hard gamma emission of B-meson, being induced at one-loop level, is an important process to search for the non-standard contributions in the low energy region. It is shown that the charged Higgs contribution can provide sizable enhancements for the weak radiative B-decay compared to the standard model. It is also found that the process such as B --> K*(1410) + gamma has the largest fraction in the exclusive radiative decays, which amounts to almost 20 %.
