本文利用欧洲核子研究中心大型强子对撞机产生的34 $\pbi$的综合光度，用ATLAS实验测量了$\sqrt{s} = 7 \TeV\ pp$碰撞的$\WW$产生截面。选择具有两个孤立轻子的事件，每个轻子都是电子或介子，观察到8个候选事件，期望背景为$1.7\pm0.6$事件。测量截面为$41^{+20}_{-16}(\ mathm {stat。}) \下午5 (\ mathrm{系统。}) \下午1 (\ mathrm{光民。})$ pb，这与QCD中按次领先顺序计算的标准模型预测$44 \pm 3$ pb一致。
This Letter presents a measurement of the $\WW$ production cross section in $\sqrt{s} = 7 \TeV\ pp$ collisions by the ATLAS experiment, using 34 $\pbi$ of integrated luminosity produced by the Large Hadron Collider at CERN. Selecting events with two isolated leptons, each either an electron or a muon, 8 candidate events are observed with an expected background of $1.7\pm0.6$ events. The measured cross section is $41^{+20}_{-16}(\mathrm{stat.})\pm 5(\mathrm{syst.})\pm 1(\mathrm{lumi.})$ pb, which is consistent with the standard model prediction of $44 \pm 3$ pb calculated at next-to-leading order in QCD.
