Constraints on Supersymmetry due to b -> s γ: an Improved Calculation
Marco A. Diaz
Abstract
The calculation of the one-loop induced decay rate b -> s γis 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 β-mA plane, imposed by the non-observation of this decay. In particular, a light CP-odd Higgs at large βbecomes allowed.
