论文摘要
Atlas观察到{Di-jets共振的横截面的限制，该横截面比}质量略低于$ \ $ \ $ \ $ 1 \ tev的预期弱。此外，CMS还报告了（非谐振）对DI-JET共振的提示，通过粒子$ y $在非常相似的质量范围内，在$ 3.6 \，$σ$（2.5 \，$σ$）上，以$ m_x \ youts $ 950 \，$ gev，$ gev。在本文中，我们表明，使用ATLAS分析中的$ M_X $使用首选范围，可以根据$ y \ to xx $的共振搜索重新诠释Di-Di-jets的CMS分析，并具有显着降低的look-elsese效果，从而使$ m_y \！\！3.6 $ \ tev te $ \ tev te te $4。 （$ 3.2 \，σ$）本地（全球）。我们提出了两个可能的紫外线完成，能够解释（di-）di-jet过度，一个包含两个标量di-quarks，另一个涉及基于$ su（3）_1 _1 \！\ times \！ su（3）_2 \！\ times \！ su（3）_3 $量规对称性，自发折断至$ su（3）$颜色。在后一种情况下，需要非扰动耦合，指向复合框架或额外的框架。实际上，使用5D-ADS时空，假设$ x $是最低的谎言共振，则获得了$ m_x/m_y $的正确质量比，并且预测三分之一的（di-）di-jet共振，质量约为$ \ of $ \ of 2.2 $ \ tev。
ATLAS observed a limit for {the cross section of di-jets resonances, which is weaker than expected for a} mass slightly below $\approx$1\TeV. In addition, CMS reported hints for the (non-resonant) pair production of di-jet resonances $X$ via a particle $Y$ at a very similar mass range with a local (global) significance of 3.6\,$σ$ (2.5\,$σ$) at $m_X\approx950\,$GeV. In this article we show that using the preferred range for $m_X$ from the ATLAS analysis, one can reinterpret the CMS analysis of di-di-jets in terms of a resonant search with $Y\to XX$, with a significantly reduced look-elsewhere effect, finding an excess for $m_Y\!\approx\!3.6$\TeV with a significance of $4.0\,σ$ ($3.2\,σ$) locally (globally). We present two possible UV completions capable of explaining the (di-)di-jet excesses, one containing two scalar di-quarks, the other one involving heavy gluons based on an $SU(3)_1\!\times\! SU(3)_2\!\times\! SU(3)_3$ gauge symmetry, spontaneously broken to $SU(3)$ color. In the latter case, non-perturbative couplings are required, pointing towards a composite or extra-dimensional framework. In fact, using 5D-AdS space-time, one obtains the correct mass ratio for $m_X/m_Y$, assuming the $X$ is the lowest lying resonance, and predicts a third (di-)di-jet resonance with a mass around $\approx2.2$\TeV.
