A Reconsideration of b→ sγ in the Minimal Flavor Violating MSSM — •Wolfgang Altmannshofer, Diego Guadagnoli, and Michael Wick — Physik Department, Technische Universität München, 85748 Garching, Germany

In the minimal flavor violating limit of the MSSM, the flavor off-diagonal elements of the squark mass matrices should be expanded in powers of the SM Yukawa couplings. This gives rise to flavor violating gluino contributions to flavor changing neutral current processes. In hep-ph/0703200 the impact of such contributions was investigated in the context of B-meson mixings.

Here we present results of a similar analysis of the process b→ s γ. We address in particular the question whether gluino contributions can naturally compensate those from charginos and Higgses, taking into account all other experimental constraints.
