Chasing the light-gluino scenario through $b\rightarrow s γ$

Abstract

We investigate the impact of a light gluino, which might have escaped detection at colliders, on inclusive radiative $B$-decays mediated through penguin-like diagrams. We find that the viability of the scenario depends largely on the magnitude of the flavour-violating $c$-parameter. Some previously allowed regions of parameter space are now ruled out.
