Measurement of hard double-parton interactions in W(l?)+ 2 jet events at s =7 TeV with the ATLAS detector
Original language description
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, collected with the ATLAS detector at the LHC. The fraction of events arising from double-parton interactions, f(D)DP has been measured through the momentum balance between the two jets and amounts to f(D)DP=0.080.01(stat.)0.02(sys.) for jets with transversemomentum PT > 20 GeV and rapidity |y|<2.8. This corresponds to a measurement of the effective area parameter for hard double-parton interactions of ?eff=153(stat.)+53 (sys.) mb.
