Study of observables sensitive to double parton scattering in W + 2 jets process in p-p collisions at sqrt(s) = 7 TeV

Double parton scattering is investigated in proton-proton collisions at a centre-of-mass energy of 7 TeV using final states including one W boson decaying into a muon and neutrino plus two associated jets. The data sample corresponds to an integrated luminosity of 5 fb$^{-1}$, collected by the CMS experiment at the LHC. Observables sensitive to the double parton scattering which can be used to discriminate against the single parton scattering process are investigated. These observables are compared with the predictions from various Monte Carlo event generators after correcting for detector effects and selection efficiency.
