Abstract:

The production of W bosons in association with two jets in proton-proton collisions at a centre-of-mass energy of √ s = 7 TeV has been analysed for the presence of double-parton interactions using data corresponding to an integrated luminosity of 36 pb -1 , collected with the ATLAS detector at the Large Hadron Collider. The fraction of events arising from double-parton interactions, f (D) DP , has been measured through the p T balance between the two jets and amounts to f (D) DP = 0.08 ±0.01 (stat.)±0.02 (sys.) for jets with transverse momentum p T > 20 GeV and rapidity |y| < 2.8. This corresponds to a measurement of the effective area parameter for hard double-parton interactions of σ eff = 15 ± 3 (stat.) +5 -3 (sys.) mb. © CERN 2013 for the benefit of the ATLAS Collaboration.
