Quarkonium production in proton–proton collision is interesting in profiling the partons inside the nucleon. Recently, the impact of double parton scatterings (DPSs) was suggested by experimental data of associated quarkonium production (J/ψ + Z, J/ψ + W, and J/ψ + J/ψ) at the LHC and Tevatron, in addition to single parton scatterings (SPSs). In this proceedings contribution, we review the extraction of the effective parameter of the DPS (σ_eff) through the evaluation of the SPS contributions under quark-hadron duality.
