Description
We propose to look for the light CP-odd state through the decay $h \to P\ell^+\ell^-$, where P stands for a pseudoscalar quarkonia. We show that the corresponding branching fraction can be enhanced as much as by a factor ~20-30 in the models with two Higgs doublets of Type I, II or X. In this study we consider $m_A < m_h$ but larger than ~20 GeV. We then show a special case of a very light CP-odd Higgs, and show how its presence can be efficiently tested through $\eta_{c,b}\to \ell \ell$ modes.
