Abstract / Description:We investigate the constraints on flavour-changing neutral heavy Higgs-boson decays H -> b \bar s from b -> s gamma bounds on the flavour-mixing parameters of the MSSM with non-minimal flavour violation (NMFV). In our analysis we include the contributions from the SM and new physics due to general flavour mixing in the squark mass matrices. We study the case of one and two non-zero flavour-mixing parameters and find that in the latter case the interference can raise the Higgs flavour-changing branching ratios by one order of magnitude with respect to previous predictions based on a single non-zero parameter and in agreement with present constraints from B physics. In the course of our work we developed a new FeynArts model file for the NMFV MSSM and added the necessary code for the evaluation to FormCalc. Both extensions are publicly available.
