Sažetak
We show that the decay rates of the Higgs boson to a pseudoscalar quarkonium and a pair of leptons, h→Pℓ+ℓ- (P∈{; ; ηc, ηb}; ; ), can be substantially enhanced in a scenario with two Higgs doublets with a softly broken Z2 symmetry [two Higgs doublet model (2HDM)] when the CP-odd Higgs A is light, i.e. mA≲mh. Depending on the type of 2HDM the enhancement of B(h→ηc, bτ+τ-) with respect to its Standard Model value can be an order of magnitude larger, i.e. O(10-6–10-5). The decays h→Pℓ+ℓ- could therefore provide an efficient channel to investigate the presence of a light CP-odd Higgs A and help to disentangle among various 2HDM scenarios.
