We study double parton scattering (DPS) processes involving electroweak gauge bosons at the 13 TeV and 100 TeV proton-proton colliders. Specifically, we focus on three DPS channels: W-boson plus two jets (W⊗ jj), Z-boson plus two jets (Z⊗ jj), and same-sign W pair production (W^±⊗ W^±). We demonstrate that the Z⊗ jj process, which has not been paid too much attentions, is the best channel for measuring effective cross section σ_ eff. The accuracy of σ_ eff measurement in the three DPS channels,
more » ... especially the W^±⊗ W^± production, is significantly improved at the 100 TeV colliders. We advocate that combined analysis of the three DPS channels could test the universality of effective cross section σ_ eff.
