给出了寻找胶子和夸克的超对称伙伴的方法，包括喷注和两个具有相同电荷的孤立轻子(电子或µ子)，或者至少三个孤立轻子的签名。利用大型强子对撞机的ATLAS探测器在2015年至2018年期间记录的=13TeV质子-质子碰撞的数据样本，对应于139fb−1的总积分光度，用于搜索。没有观察到明显超过标准模型预期的情况。结果在具有R宇称守恒和R宇称破坏的简化超对称模型中得到解释，在这些情况下，将排除限制提高到了以前ATLAS搜索的胶子质量为1600GeV，底部和顶部夸克质量为750GeV。
A search for supersymmetric partners of gluons and quarks is presented, involving signatures with jets and either two isolated leptons (electrons or muons) with the same electric charge, or at least three isolated leptons. A data sample of proton-proton collisions at= 13 TeV recorded with the ATLAS detector at the Large Hadron Collider between 2015 and 2018, corresponding to a total integrated luminosity of 139 fb− 1, is used for the search. No significant excess over the Standard Model expectation is observed. The results are interpreted in simplified supersymmetric models featuring both R-parity conservation and R-parity violation, raising the exclusion limits beyond those of previous ATLAS searches to 1600 GeV for gluino masses and 750 GeV for bottom and top squark masses in these scenarios.
