Description

Rather than sticking to the full U(3)^3 approximate symmetry normally invoked in Minimal Flavour Violation, we analyze the consequences on the current flavour data of a suitably broken U(2)^3 symmetry acting on the first two generations of quarks and squarks. A definite correlation emerges between the mixing amplitudes in the K, B_d and B_s systems, which can resolve the current tension in the CKM fit, while predicting the B_s mixing phase. The preferred region for the gluino and the left-handed sbottom masses is below about 1 to 1.5 TeV.
