Exploring two Higgs doublet models through Higgs production

We discuss the connections between the recently observed Higgs-like particle and rare B decays in the context of two Higgs doublet models (2HDMs). The measured decays of the Higgs boson to fermions and gauge bosons, along with the observation of the decay Bₛ→μ⁺μ^-, place stringent restrictions on the allowed parameter space of two Higgs doublet models. Future measurements of h⁰→γγ can potentially exclude Type I 2HDMs, while the parameters of other 2HDMs are already severely restricted. The recent observations of the h⁰→τ⁺τ^- and h⁰→bb̄ decays further constrain the models.
