What the Tevatron Found?

摘要:

CDF合作组已经报道了他们的轻子、丢失能量和双射流通道中的4.1σ过剩。这种过剩,它采取的形式近似高斯峰为中心的dijet不变质量为147 GeV,引起了大量的实验和理论的兴趣。虽然DALLESS合作报告说,他们没有观察到与CDF一致的信号,但目前还没有广泛接受的解释这两个实验之间的差异。这个问题的解决是非常重要的-不仅仅是因为它可以教我们与未来在大型强子对撞机上的搜索相关的教训-而且它显然需要更多的信息。在本文中,我们认为Tevatron和LHC探测器的能力,观察与CDF过剩在各种渠道的证据。我们还讨论了选定的运动学分布的能力,以区分标准模型的解释所观察到的过剩和各种新的物理方案。

英文摘要:

The CDF collaboration has reported a 4.1σ excess in their lepton, missing energy, and dijets channel. This excess, which takes the form of an approximately Gaussian peak centered at a dijet invariant mass of 147 GeV, has provoked a great deal of experimental and theoretical interest. Although the DØ collaboration has reported that they do not observe a signal consistent with CDF, there is currently no widely accepted explanation for the discrepancy between these two experiments. A resolution of this issue is of great importance---not least because it may teach us lessons relevant for future searches at the LHC---and it will clearly require additional information. In this paper, we consider the ability of the Tevatron and LHC detectors to observe evidence associated with the CDF excess in a variety of channels. We also discuss the ability of selected kinematic distributions to distinguish between Standard Model explanations of the observed excess and various new physics scenarios.
