A note on Higgs decays into Z boson and J/Ψ(ϒ)
Rare decays h→ZV with V denoting the narrow cc¯ or bb¯ resonances, such as J/Ψ or ϒ states, have been analyzed. Within the standard model, these channels may proceed through the tree-level transition h→ZZ⁎ with the virtual Z⁎→V, and also loop-induced process h→Zγ⁎, followed by γ⁎→V. Our analysis sho...
