Phenomenology of SUSY with General Flavour Violation

Abstract

We discuss the consequences of relaxing the Minimal Flavour Violation assumption in the up-squark sector on the phenomenology of SUSY models. We study the impact of the off-diagonal entries in the soft SUSY-breaking matrices on the mass of the lightest Higgs scalar and we derive the approximate analytical formulae that quantify this effect. We show that $m_h$ can be enhanced by up to 13-14 GeV in the case of the phenomenological MSSM with the inverted hierarchy of masses in the squark sector and zero stop mixing, and up to 4-5 GeV in GUT-constrained scenarios where the magnitude of the enhancement is mitigated by renormalization group effects. We also perform a global analysis of an inverted hierarchy GFV scenario, taking into account the experimental bounds from the measurements of relic density, EW precision observables and B-physics. We show that the allowed parameter space of the model is strongly constrained by $m_W$, ${\sin }^2{\theta }_{eff}$ and $BR(B_s\to {\mu }^{+}{\mu }^{-})$, requiring $m_0(3)$<1500 GeV and $m_{1/2}$<1800 GeV, as well as a large non-zero (2,3) entry in the up-squark trilinear matrix.
