使用 LHC 的 ATLAS 探测器记录的 √s = 7 TeV 处的 4.6 fb-1of 质子-质子碰撞数据，研究了与 W 或 Z 玻色子衰变为两个喷流相关的 W 玻色子衰变为 eν 或 μν 的产生。测量的组合 WW + WZ 横截面显着性为 3.4σ，结果为 68±7（统计）±19（系统）pb，与标准模型预期的 61.1±2.2 pb 一致。双喷射系统的横向动量分布用于设置对三规范耦合顶点的异常贡献和有效场论模型的参数的限制。
The production of a W boson decaying to eν or μν in association with a W or Z boson decaying to two jets is studied using 4.6 fb-1of proton-proton collision data at √s = 7 TeV recorded with the ATLAS detector at the LHC. The combined WW + WZ cross section is measured with a significance of 3.4σ and is found to be 68±7 (stat.)±19 (syst.)pb, in agreement with the Standard Model expectation of 61.1±2.2 pb. The distribution of the transverse momentum of the dijet system is used to set limits on anomalous contributions to the triple gauge coupling vertices and on parameters of an effective-field-theory model.
