Abstract

We perform a complete computation of the contributions to b → s + γ, b → s/⁺/^-, b → sνν, b → s + g, B_d^o-B_d^o and B_{s^o-B_s^o} 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.
