We study double parton scattering (DPS) processes involving electroweak gauge bosons at the 13 and 100 TeV proton-proton colliders. Specifically, we focus on three DPS channels: W-boson plus two jets (Wjj), Z-boson plus two jets (Zjj), and same-sign W pair production (W±W±). We demonstrate that the Zjj process, which has not received much attention, is the best channel for measuring the effective cross section σeff. The accuracy of the σeff measurement in the three DPS channels, 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 the effective cross section σeff.
