Wj j中CDF双射流过剩的标准模型解释

Standard model explanation of a CDF dijet excess in Wjj

Zack Sullivan, Arjun Menon

摘要:

我们证明了最近观察到的峰值的双喷流不变质量的Wjj信号观察到的CDF合作可以解释为相同的向上波动观察CDF在单顶夸克生产。一般来说,t-通道和s-通道单顶夸克的产生都会在双喷流谱中产生运动学诱导的峰。由于CDF使用了蒙特卡罗模拟来减去单顶背景而不是数据,因此预期双射流光谱中会出现峰值。D 0协作组在其公布的t通道数据中有一个小的向上波动;因此,我们预测,如果他们遵循与CDF相同的程序,他们最多会在Wjj的双喷射不变量质谱中看到一个小峰。

英文摘要:

We demonstrate the recent observation of a peak in the dijet invariant mass of the Wjj signal observed by the CDF Collaboration can be explained as the same upward fluctuation observed by CDF in single-top-quark production. In general, both t-channel and s-channel single-top-quark production produce kinematically induced peaks in the dijet spectrum. Since CDF used a Monte Carlo simulation to subtract the single-top backgrounds instead of data, a peak in the dijet spectrum is expected. The D0 Collaboration has a small upward fluctuation in their published t-channel data; and hence we predict they would see at most a small peak in the dijet invariant mass spectrum of Wjj if they follow the same procedure as CDF.
