Measurement of hard double-parton interactions in W(→ lν) + 2-jet events at √s = 7 TeV with the ATLAS detector

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 L...
