标题： Search for resonant diboson production in the lvjj decay channels with the ATLAS detector at 7 TeV

摘要： 使用对应于在7 TeV质子对撞中由ATLAS实验收集的4.7 fb-1积分亮度的数据样本，进行寻找共振双玻色子产生的研究。在最终状态包含一个电子或缪子、缺失横向动量以及至少两个喷注的情况下，对WW或WZ质量分布中的窄共振进行搜索。未观察到显著过剩，并使用三种基准模型设置限制：对于自旋-2 Randall-Sundrum和体 Randall-Sundrum 引力子，低于940 GeV和710 GeV的WW共振质量分别在95%置信水平下被排除；对于自旋-1扩展规范模型W'玻色子，低于950 GeV的WZ共振质量在95%置信水平下被排除。 显示英文摘要

摘要： A search for resonant diboson production using a data sample corresponding to 4.7 fb-1 of integrated luminosity collected by the ATLAS experiment at the Large Hadron Collider in pp collisions at 7 TeV is presented. The search for a narrow resonance in the WW or WZ mass 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: WW resonance masses below 940 GeV and 710 GeV are excluded at 95% confidence level for spin-2 Randall-Sundrum and bulk Randall-Sundrum gravitons, respectively; WZ resonance masses below 950 GeV are excluded at 95% confidence level for a spin-1 Extended Gauge Model W' boson.
