摘要：

我们提出了CMS 5 \fb全强子搜索采用横向质量变量$M_{T2}$和ATLAS 5 \fb全强子和多喷流超对称（SUSY）搜索之间的明确相关性，这表明ATLAS和CMS实验都已经在LHC上记录了微弱但合法的SUSY信号的可能性。我们在超对称无标度翻转$SU$（5）大统一理论的框架中，用额外的类矢量物质（翻转子）补充，将这种预期的相互生产力隔离在标准模型之外。在三个CMS \mt 2和四个ATLAS强子和多喷流信号区观察到明显的生产过剩，其中CMS 5 \fb \mt 2搜索的\x 2拟合程序建立了与相应的ATLAS搜索相当提高信号显著性的最佳拟合SUSY质量。我们相信，在完全相同的超对称质量尺度下，两个不同实验的这种相关行为是非常重要的，并可能表明现有的5 \fb LHC进入了一个普遍的物理超对称框架。

英文摘要：

We present definite correlations between the CMS 5 \fb all-hadronic search employing the stransverse mass variable $M_{T2}$ and the ATLAS 5 \fb all-hadronic and multijet supersymmetry (SUSY) searches, suggesting the possibility that both the ATLAS and CMS experiments are already registering a faint but legitimate SUSY signal at the LHC. We isolate this prospective mutual productivity beyond the Standard Model in the framework of the supersymmetric No-Scale Flipped $SU$(5) grand unified theory, supplemented with extra vector-like matter (flippons). Evident overproduction is observed in three CMS \mt2 and four ATLAS hadronic and multijet signal regions, where a \x2 fitting procedure of the CMS 5 \fb \mt2 search establishes a best fit SUSY mass in sharp agreement with corresponding ATLAS searches of equivalently heightened signal significance. We believe this correlated behavior across two distinct experiments at precisely the same SUSY mass scale to be highly non-trivial, and potentially indicative of an existing 5 \fb LHC reach into a pervasive physical supersymmetry framework.
