On the h → Vℓ+ ℓ− decays

A set of exclusive decay of the Higgs boson into a vector meson and a dilepton pair (h → Vℓ+ ℓ−, with V = ϒ, J/ψ, ϕ, and ℓ = μ, τ) 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 → Vvv̄ and the implications of the CMS and ATLAS results for the lepton flavor-changing process h → τ+ μ− on the h → Vτ+ μ− decay modes
