On Exclusive $h\to V{\ell }^{+}{\ell }^{-}$ Decays

Abstract

We study a set of exclusive decay modes of the Standard Model Higgs boson into a vector meson and a dilepton pair: $h\to V{\ell }^{+}{\ell }^{-}$, with $V={\rm Y},J/\psi ,\varphi$, and $\ell =\mu ,\tau$, determining the decay rates, the dilepton mass spectra and the $V$ longitudinal helicity fraction distributions. In the same framework, we analyze the exclusive modes into neutrino pairs $h\to V\nu \bar{\nu }$. We also discuss the implications of the recent CMS and ATLAS results for the lepton flavor-changing process $h\to {\tau }^{+}{\mu }^{-}$ on the $h\to V{\tau }^{+}{\mu }^{-}$ decay modes.
