Description

In this talk we show the effects of adding a second Higgs doublet to the SM particle content on flavour observables. After updating the constraints of the 2HDM of type II (which respects natural flavour conservation) we constrain the flavour structure of the 2HDM of type III (with general Yukawa coupling) from FCNC processes. Interestingly, respecting these constraints, sizable effects in B->tau nu and B->D(*) tau are possible and in all three decays the tensions between the SM and experiment can be removed.
