Pair production of quarkonia and electroweak bosons from double-parton scatterings in nuclear collisions at the LHC

Cross sections for the concurrent production of pairs of quarkonia (J/ψ,ϒ) and/or W, Z gauge bosons from double-parton scatterings (DPS) in high-energy proton–nucleus and nucleus–nucleus collisions at the LHC are calculated. The estimates are based on next-to-leading-order perturbative QCD predictions, including nuclear modifications of the parton densities, for the corresponding single-scattering cross sections. Expected event rates for J/ψ+J/ψ, J/ψ+ϒ, J/ψ+W, J/ψ+Z, ϒ+ϒ, ϒ+W, ϒ+Z, and same-sign W+W production in their (di)leptonic decay modes, after typical acceptance and efficiency losses, are given for p–Pb and Pb–Pb collisions
