We present a measurement of the W(+)W(-) production cross section using 184 pb(-1) of p(p) collisions at a center-of-mass energy of 1.96 TeV collected with the Collider Detector at Fermilab. Using the dilepton decay channel W(+)W(-)-->l(+)nul(-), where the charged leptons can be either electrons or muons, we find 17 candidate events compared to an expected background of 5.0(+2.2)(-0.8) events. The resulting W(+)W(-) production cross-section measurement of sigma(pp-->W(+)W(-))=14.6(+5.8)(-5.1)(stat)(+1.8)(-3.0)(syst) +/- 0.9(lum) pb agrees well with the standard model expectation.
我们展示了使用费米实验室对撞机探测器收集的质心能量为1.96 TeV的184 pb⁻¹ 的质子-质子（p-p）碰撞数据测量W⁺W⁻产生截面的结果。利用双轻子衰变道W⁺W⁻→l⁺νl⁻，其中带电轻子可以是电子或μ子，我们发现了17个候选事例，而预期本底为5.0（+2.2）（-0.8）个事例。由此得到的W⁺W⁻产生截面测量值σ（pp→W⁺W⁻）=14.6（+5.8）（-5.1）（统计）（+1.8）（-3.0）（系统）±0.9（光度）pb，与标准模型预期符合得很好。
