Description

We investigate the MSSM with very large tan(beta) > 50, where the fermion masses are strongly affected by loop-induced couplings to the "wrong" Higgs, imposing perturbative Yukawa couplings and constraints from flavour physics. Performing a low-energy scan of the MSSM with flavour-blind soft terms, we find that the branching ratio of B->tau nu and the anomalous magnetic moment of the muon are the strongest constraints at very large tan(beta) and identify the viable regions in parameter space. We also analyse the very large tan(beta) regime of General Gauge Mediation (GGM) with a low mediation scale. We point out that the possibility of a vanishing Bmu term at the mediation scale M, the "uplifted SUSY" scenario, is challenged by the experimental data on B->tau nu and the anomalous magnetic moment of the muon if M = 100 TeV.
