摘要
Two hard parton-parton interactions in a single proton-proton (pp) collison lead to double parton scattering (DPS). We investigate DPS in pp collisions at root s = 7TeV where the final state includes a W boson, which decays into a muon and a neutrino, and two jets. Various observables sensitive to double parton scattering are investigated after being corrected for detector effects and selection efficiencies. The fraction of W + 2-jet events due to double parton scattering as well as the effective transverse area (sigma(eff)) of the hard partonic interaction in the pp collision has been measured with the CMS experiment, using data collected at 7TeV of center-of-mas energy corresponding to an integrated luminosity of 5 fb(-1). Studies for the invariance of seff with centre-of-mass energy, scale and different processes will also be presented in this talk, which are performed using the simulated events from Monte Carlo Event generator PYTHIA8.
