Investigating the light-gluino scenario through b→sγ

Abstract

We investigate the impact of a light gluino, which might have escaped detection at colliders, on inclusive radiative B decays mediated through penguinlike diagrams. We find that the viability of the scenario depends largely on the magnitude of the flavor-violating c parameter and on the charged Higgs boson mass. Some previously allowed regions of parameter space are now disfavored.
