Seeking the CP-odd Higgs via $h\to {\eta }_{c,b}{\ell }^{+}{\ell }^{-}$

Damir Bečirević, Blaženka Melić, Monalisa Patra +1

We show that the decay rates of the Higgs boson to a pseudoscalar quarkonium and a pair of leptons, $h\to P{\ell }^{+}{\ell }^{-}$ ($P\in \{{\eta }_c,{\eta }_b\}$), can be substantially enhanced in a sce…
