Search for a lighter Higgs in Two Higgs Doublet Models

Abstract : We consider present constraints on two Higgs doublet models, both from the LHC at Run 1 and from other sources in order to explore the possibility of constraining a neutral scalar or pseudoscalar particle lighter than the 125 GeV Higgs boson. Contrary to naive expectations, such a lighter particle is not yet completely excluded by present data. We show with a simplified analysis that some new constraints could be obtained at the LHC if such a search is performed by the experimental collaborations.
