| dc.description.abstract | The production of W bosons in association with two jets in proton-proton collisions at a centre-of-mass energy of $\sqrt{s}$=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, $f_{DP}^{(D)}$ has been measured through the momentum balance between the two jets and amounts to $f_{DP}^{(D)} = 0.08 \pm 0.01 (stat.) \pm 0.02 (sys.)$ for jets with transverse momentum PT > 20 GeV and rapidity |y|<2.8. This corresponds to a measurement of the effective area parameter for hard double-parton interactions of $\sigma_{eff} = 15 \pm 3 (stat.)^{+5}_{-3}$ (sys.) mb. | |
