$Z$-boson decays to a vector quarkonium plus a photon

We compute the decay rates for the processes Z→V+γ, where Z is the Z-boson, γ is the photon, and V is one of the vector quarkonia J/ψ or ϒ(nS), with n=1, 2, or 3. Our computations include corrections through relative orders αs and v2 and resummations of logarithms of mZ2/mQ2, to all orders in αs, at...
