Flavour violation in a supersymmetric T' model

Abstract

We describe the phenomenology of the flavour changing neutral current sector of a supersymmetric model, invariant under the T' discrete flavour group. This model has been proposed in Ref.[1] and describes realistic leptonic and hadronic masses and mixings and predicts the amount of flavour changing in terms of the small flavour breaking parameter u in [0.007, 0.05]. For small values of u, the model almost reduces to the MSUGRA framework, while sizable deviations from MSUGRA can be, instead, observed when larger values of u and tan(beta) are considered. We analyse in detail the T' BR(mu --> e gamma) prediction, concerning the leptonic sector, while for the hadronic sector we concentrate on b --> s gamma and neutral B meson mass differences. Moreover, for the first time a comparative study on leptonic and hadronic observables for the T' model is performed. The experimental data on FCNC observables severely constrain the model in the small m_0 region. Conversely for larger m_0, the T' model satisfies all the bounds.
