CDF $Wjj$异常的LHC测试

LHC Test of CDF $Wjj$ anomaly

Keisuke Harigaya, Ryosuke Sato, Satoshi Shirai

摘要:

我们讨论的CDF dijet异常在LHC的测试。最近在CDF观测到的双喷流质量峰与一种质量约为150 GeV的新粒子很好地拟合,这种粒子衰变为两个喷流。在本文中,我们专注于只有$Wjj$信号,以避免模型依赖,全面研究LHC的发现/排除达到。我们发现几乎所有的模型都与LHC的结果不一致,除非只有价夸克贡献了新的过程。我们还讨论了LHC搜索这种异常的进一步前景。

英文摘要:

We discuss a test of the CDF dijet anomaly at the LHC. The recent observed dijet mass peak at the CDF is well fitted by a new particle with a mass of around 150 GeV, which decays into two jets. In this paper, we focus on only $Wjj$ signal to avoid model dependence, and comprehensively study the LHC discovery/exclusion reach. We found almost all the models are inconsistent with the result of the LHC, unless only valence quarks contribute the new process. We also discuss further prospects of the LHC search for this anomaly.
