We present a measurement of the W boson pair-production cross section in pp collisions at a center-of-mass energy of sqrt[s]=1.96 TeV. The data, collected with the Run II D0 detector at Fermilab, correspond to an integrated luminosity of 224-252 pb(-1) depending on the final state (ee, emu, or mumu). We observe 25 candidates with a background expectation of 8.1+/-0.6(stat)+/-0.6(syst)+/-0.5(lum) events. The probability for an upward fluctuation of the background to produce the observed signal is 2.3x10(-7), equivalent to 5.2 standard deviations. The measurement yields a cross section of 13.8(+4.3)(-3.8)(stat)+1.2-0.9(syst)+/-0.9(lum) pb, in agreement with predictions from the standard model.
我们给出了在质心能量为√s = 1.96 TeV的质子-质子碰撞中W玻色子对产生截面的测量结果。使用费米实验室的Run II D0探测器收集的数据，根据末态（ee、emu或mumu）的不同，对应的积分亮度为224 - 252 pb⁻¹。我们观测到25个候选事例，背景预期为8.1±0.6（统计）±0.6（系统）±0.5（亮度）个事例。背景向上波动产生观测到的信号的概率为2.3×10⁻⁷，相当于5.2个标准差。该测量得到的截面为13.8（+4.3）（-3.8）（统计）+1.2 - 0.9（系统）±0.9（亮度）pb，与标准模型的预测相符。
