Study of hard double-parton scattering in four-jet events in pp collisions at √s=7 TeV with the ATLAS experiment

Original language description

Inclusive four-jet events produced in proton-proton collisions at a centre-of-mass energy of s√=7 TeV are analysed for the presence of hard double-parton scattering using data corresponding to an integrated luminosity of 37.3 pb−1, collected with the ATLAS detector at the LHC. The contribution of hard double-parton scattering to the production of four-jet events is extracted using an artificial neural network, assuming that hard double-parton scattering can be approximated by an uncorrelated overlaying of dijet events. For events containing at least four jets with transverse momentum pT ≥ 20 GeV and pseudorapidity |η| ≤ 4.4, and at least one having pT ≥ 42.5 GeV, the contribution of hard double-parton scattering is estimated to be fDPS = 0.092+ 0.005− 0.011 (stat.)+ 0.033− 0.037 (syst.).
