摘要：

假设CDF协作组在Wjj生产中发现的150 Gev附近的双喷流过剩是由于低尺度人工色过程$ρ_T \rightarrow W π_T$的最轻技术引起的，我们用1-5 fb^{-1}的数据研究了它在LHC探测器中的可观测性。我们发现，类似于CDF所采用的削减不太可能证实其信号。我们建议削减量身定制的LSTC假设和它的背景在LHC，可以揭示$π_T \rightarrow jj$。我们还强调了与同位旋相关的通道$ρ^{\pm}_T \rightarrow Zπ^{\pm}_T \rightarrow \ell\ell jj$和全轻子模式$ρ^{pm}_T \rightarrow WZ \rightarrow 3\ell + ν$在LHC中的重要性。

英文摘要：

Under the assumption that the dijet excess seen by the CDF Collaboration near 150 Gev in Wjj production is due to the lightest technipion of the low-scale technicolor process $ρ_T \rightarrow W π_T$, we study its observability in LHC detectors with 1-5 fb^{-1} of data. We find that cuts similar to those employed by CDF are unlikely to confirm its signal. We propose cuts tailored to the LSTC hypothesis and its backgrounds at the LHC that can reveal $π_T \rightarrow jj$. We also stress the importance at the LHC of the isospin-related channel $ρ^{\pm}_T \rightarrow Zπ^{\pm}_T \rightarrow \ell\ell jj$ and the all-lepton mode $ρ^{pm}_T \rightarrow WZ \rightarrow 3\ell + ν$.
