dc.description.abstract | 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 |?| ? 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? 0.011 + 0.005(stat.)? 0.037 + 0.033(syst.). After combining this measurement with those of the inclusive dijet and four-jet cross-sections in the appropriate phase space regions, the effective cross-section, ?eff , was determined to be ?eff = 14. 9? 1.0 + 1.2(stat.)? 3.8 + 5.1(syst.) mb. This result is consistent within the quoted uncertainties with previous measurements of ?eff , performed at centre-of-mass energies between 63 GeV and 8 TeV using various final states, and it corresponds to 21? 6 + 7 % of the total inelastic cross-section measured at s=7 TeV. The distributions of the observables sensitive to the contribution of hard double-parton scattering, corrected for detector effects, are also provided.[Figure not available: see fulltext.] © 2016, The Author(s). | en_US |
