The inclusive production of four isolated charged leptons in pp collisions is analysed for the presence of hard double-parton scattering, using a dataset corresponding to 20.2 fb-1, recorded with the ATLAS detector at the LHC at centre-of-mass energy of 8 TeV. In the four-lepton invariant-mass range of 80 < M4l < 1000 GeV, an artificial neural network is used to enhance the separation between...
