Fiducial cross-section for Wt+tˉt production in events with two leptons and exactly one jet, using an integrated luminosity of 20.3 fb−1 of proton-proton collisions at a centre-of-mass energy of 8 TeV at the Large Hadron Collider, collected with the ATLAS detector. The cross-section for the production of a top quark and a W boson is measured in a fiducial acceptance requiring two leptons with p⊥>25 GeV and |η|<2.5, one jet with p⊥>20 GeV and |η|<2.5, and EmissT>20 GeV, including both Wt and top-quark pair events as signal. The measured value of the fiducial cross-section is 0.85±0.01 (stat.) ±0.07 (syst.) ±0.03 (lumi.) pb.
