The two-loop gluino's corrections on the inclusive b ---> x(s) gamma decay in the CP violation MSSM with large tan beta

Abstract

We investigate two-loop gluino corrections to the effective Lagrangian for b ! s g in the minimal supersymmetric extension of the standard model (MSSM) at large tan , including the contributions in which quark flavor change is mediated by charginos. Using the translation invariance of loop momenta and the Ward-Takahashi identities that are required by the SU3 c U1 em gauge invariance, we simplify our expressions to concise forms. As an example, we discuss two-loop gluino corrections to the CP asymmetry of inclusive B ! Xs decay in CP violating MSSM.
