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^-1, collected in 2010 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 +- 0.01 (stat.) +- 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 +- 3 (stat.) +5,-3 (sys.) mb.\n\nData points reverse engineered from Figure 9 of paper by Evgeny Slavin.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.63897.v1/t1","@type":"Dataset","description":"Distribution of Delta(jets,normalised), defined in Eq.
