Improved analysis of rare Z-boson decays into a heavy vector quarkonium plus lepton pair
We improve the theoretical predictions for rare Z-boson decays, Z→Vℓ+ℓ− (ℓ=e or μ), where V denotes a heavy vector quarkonium including J/Ψ, Ψ(2S), and Υ(nS) with n=1,2,3. These processes are thought to be dominated by the electromagnetic fragmentation transition, i.e., Z→γ*ℓ+ℓ− followed by γ* → V....
