Description

Searches for the kinematic selection criteria for estimation of multiple parton interaction fraction in pp collisions at \sqrt{s} = 14 TeV are presented using the eikonalization of the cross section implemented in the HERWIG++ MC generator. W^+ boson pair production is studied in the muon decay channel. Four types of the main background processes are discussed and analyzed. These include W^+W^+jj, W^+Z, ZZ, and ttbar productions of the positively charged muon pairs. The double parton scattering contribution to the requested di-muon final state is found to be around 25 per cent with the production cross section of 0.94 fb.
