Abstract

In SUSY, the MFV framework is usually called upon in order to ameliorate the New Physics contribution to FCNC. However, this framework, based on a U(3)³ flavour symmetry, is insufficient to solve current tensions in ΔF = 2 processes related to CP Violation. In this work, we analyze the consequences of reducing the symmetry down to a U(2)³ acting on the two lighter generations. We shall outline the U(2)³ framework, and show how it can resolve the current tension between K⁰→K ⁰ and B⁰ →B ⁰mixing, predicting at the same time a larger phase in B⁰ _s →B⁰ _s mixing.
