Abstract

We perform a complete computation of the contributions to b → s + γ, b → s/+/-, b → sνν, b → s + g, Bdo -Bdo and Bso-Bso in minimal spontaneously broken N = 1 supergravity with radiative breaking of the electroweak symmetry group. We compare our results with previous evaluations in non-minimal and minimal supersymmetric models, where the constraint of the SU(2)L × U(1)Y radiative breaking was not imposed. The possibilities of disentangling supersymmetry from the Standard Model in the experimental searches for the abovementioned rare processes are discussed.
