Selecting events with two isolated leptons, each either an electron or a muon, 8 candidate events are observed with an expected background of 1.7 +/- 0.6 events. The measured cross section is 41(-16)(+20)(stat) +/- 5(syst) +/- 1(lumi) pb, which is consistent with the standard model prediction of 44 +/- 3 pb calculated at next-to-leading order in QCD. %R 10.1103/PhysRevLett.107.041802 %U http://arxiv.org/abs/arXiv:1104.5225 %U https://doi.org/10.1103/PhysRevLett.107.041802 %P 041802-18pp
