The effect of H± on B± → τ±ντ and B± → μ±νμ

The hitherto unobserved purely leptonic decays B± → τ±ντ and B± → μ±νμ are of much interest in current and future runs of the e+eB factories. Such decays are sensitive to charged Higgs bosons (H±) at the tree-level and provide important constraints on tan β/mH±. We include the large corrections to the H±ub coupling induced by virtual SUSY effects and show that the bounds on tan β/mH± can be significantly weakened or strengthened.
