Footprints of SUSY GUTs in avour physics

Supersymmetric (SUSY) Grand Unifed theories (GUTs) generally predictFCNC and CP violating processes to occur both in the leptonic and hadronic sectors.Assuming an underlying SU(5) group plus right-handed neutrinos (RN), we perform anextensive study of FCNC and CP violation, analyzing the correlations between leptonicand hadronic processes like μ → e γ and K ⁰ - K̄⁰ mixing, τ → μγ and b → s transitionssuch as Bd → Ks and B⁰s-̄B⁰s mixing. Moreover, we examine the impact of the consideredscenario on the UT analyses, monitoring the low energy consequences implied by possiblesolutions to the various tensions in the present UT analyses. We compare the phenomenologicalimplications of this NP scenario with the ones of supersymmetric avour modelsnding a few striking differences that could allow to distinguish these different NP models.
