On the $h\to V{\ell }^{+}{\ell }^{-}$ decays

Abstract

A set of exclusive decays of the Higgs boson into a vector meson and a dilepton pair ($h\to V{\ell }^{+}{\ell }^{-}$, with $V={\rm Y},J/\psi ,\varphi$, and $\ell =\mu ,\tau$) are studied in the framework of the Standard Model. We have evaluated the decay rates, the dilepton mass spectra and the $V$ longitudinal helicity fraction distributions. In the same framework, we considered the exclusive modes $h\to V\nu \bar{\nu }$ and the implications of the CMS and ATLAS results for the lepton flavor-changing process $h\to {\tau }^{+}{\mu }^{-}$ on the $h\to V{\tau }^{+}{\mu }^{-}$ decay modes.
