Beschreibung

In singlet extensions of the two Higgs doublet model, a light CP-odd Higgs boson (A) can significantly modify decay modes of the charged Higgs. We study a scenario in which the charged Higgs is produced in top quark decays, t -> H+ b, with dominant H+ -> W+ A. We discuss search strategies based on A -> tau tau and on the subleading decay mode A -> mu mu. We show that the searches we propose can constrain, with 20 fb^−1 of 8TeV LHC data, most of the currently allowed parameter space and that existing trilepton searches are not sensitive to this signal due to the adopted isolation criteria.
