Seeking a light CP-odd Higgs state

Exclusive decays of the Higgs boson to a pseudoscalar quarkonium and a pair of leptons, h -> eta_{; ; ; c ; b}; ; ; l+ l- are rare and can be substantially enhanced in a scenario which includes a light CP-odd Higgs A (mA <= mh) which makes them experimentally appealing. We illustrate that feature in two Higgs doublet models (2HDM) and show that Br(h -> eta(c ; b) tau+ tau-) can be an order of magnitude larger than in the Standard Model, i.e. O(10^(-6) - 10^(-5)).
