摘要：
The calculation of the one-loop induced decay rate b --> sgamma is improved by including radiative corrections to the charged Higgs mass and to the charged-Higgs-fermion-fermion vertex. It is shown how the radiative corrections modify the excluded zone in the tan beta - m(A) plane, imposed by the non-observation of this decay. In particular, a light CP-odd Higgs at large tan beta becomes allowed.
