Abstract
We show that the decay rates of the Higgs boson to a pseudoscalar quarkonium and a pair of leptons, (), can be substantially enhanced in a scenario with two Higgs doublets with a softly broken symmetry [two Higgs doublet model (2HDM)] when the -odd Higgs is light, i.e. . Depending on the type of 2HDM the enhancement of with respect to its Standard Model value can be an order of magnitude larger, i.e. . The decays could therefore provide an efficient channel to investigate the presence of a light -odd Higgs and help to disentangle among various 2HDM scenarios.
