Abstract

In these proceedings we review the impact of additional Higgs bosons on B physics observables. For this purpose, we consider first the 2HDM of type II which respects natural flavour conservation. Afterwards, we study a 2HDM with generic flavour structure (of type III). While constraints from B_s,d→μ⁺μ⁺ impose stringent bounds on non-minimal flavour violation in the down sector, b→ s,dγ can also constrain flavour violation in the up sector. Despite these stringent constraints and the recent CMS bounds from A⁰→τ⁺τ^- it is shown that still large effects in tauonic B decays are possible, such that the BABAR measurements of these decays can be explained. The matching of the Yukawa sector of the MSSM on the 2HDM is discussed.
