Description

We study double parton scattering (DPS) processes in gauge boson plus two jets ($W/Zjj$) final state and same sign W bosons ($W^\pm W^\pm$) final state at pp-collider with $\sqrt{s}= 13$ TeV and 100 TeV. We compare two different double parton models. After that, we discuss the kinematic distribution features of DPS events, showing the existence of distinctive observables, which can be used to separate DPS from the single parton scattering backgrounds. The crucial physical quantity in DPS, $\sigma_{\rm eff}$ , is under detailed research in this work. The possibility of DPS being background of standard model processes is also studied.
