Popis: We study a set of exclusive decay modes of the Standard Model Higgs boson into a vector meson and a dilepton pair: h→Vℓ+ℓ−, with V=ϒ,J/ψ,ϕ, and ℓ=μ,τ, 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→Vνν¯. We also discuss the implications of the recent CMS and ATLAS results for the lepton flavor-changing process h→τ+μ− on the h→Vτ+μ− decay modes.
