Description
The double parton scattering (DPS) in proton-proton collisions at a center-of-mass energy of 8 TeV has been investigated using various final states. Multi-Jet, including b-jets, photon-jets as well as same-sign W bosons with each W boson decaying into muon and associated neutrino. The observables most sensitive to double parton scattering are defined and studied. A multivariate analysis is developed in order to enhance the DPS sensitivity. A limit on the DPS yield has been evaluated.
