Abstract

In these proceedings we review the impact of the tauonic B decays B→τν, B→ Dτν and B→ D^*τν on Higgs mediated flavour violation. For this purpose we study a 2HDM with generic flavour structure (of type III). We find that despite the stringent constraints from FCNC processes sizable effects in tauonic B decays are possible if top-related flavour violation is large and that the tensions with the SM predictions can be resolved even when taking into account the recent CMS bounds on A⁰→τ⁺τ^-.
