给出了用ATLAS实验在大型强子对撞机碰撞中收集的积分光度的数据样本来寻找共振双玻色子的产生。在理论质量分布中寻找窄共振是在有一个电子或一个介子、失去横向动量和至少两个喷注的最终状态下进行的。没有观察到显著的过剩，并使用三个基准模型设置了限制：对于自旋2的Randall-Sundrum和整体的Randall-Sundrum引力子，分别在95%的置信度下排除了低于940和710 GeV的共振质量；对于自旋1的扩展规范模型玻色子，在95%的置信度下排除了低于950 GeV的共振质量。
A search for resonant diboson production using a data sample corresponding toof integrated luminosity collected by the ATLAS experiment at the Large Hadron Collider incollisions at <?format ?>is presented. The search for a narrow resonance in theormass distribution is conducted in a final state with an electron or a muon, missing transverse momentum, and at least two jets. No significant excess is observed and limits are set using three benchmark models:resonance masses below 940 and 710 GeV are excluded at 95% confidence level for spin-2 Randall–Sundrum and bulk Randall–Sundrum gravitons, respectively;resonance masses below 950 GeV are excluded at 95% confidence level for a spin-1 extended gauge modelboson.
