FLAVOUR SYMMETRIES AND SUSY SOFT BREAKING AT THE LHC

摘要

Supersymmetry is one of the best options among the possible extensions of the SM that can be found at the LHC. However, most of the phenomenological analysis have been done neglecting flavour structures. In this paper, we show that a realistic flavour symmetry can simultaneously explain the flavour structures in the Yukawa matrices and solve the so-called SUSY flavour problem without ad hoc modifications of the SUSY model. Furthermore, departures from the SM expectations in these models can be used to discriminate among different possibilities. We find that large contributions can be expected in lepton flavour violating decays, as μ→eγ and τ→μγ, electric dipole moments, d_e and d_n and kaon CP-violating processes as ε_K. Thus, these flavoured MSSM realizations are phenomenologically sensitive to the experimental searches in the realm of flavour and CP violation physics.
