用ATLAS探测器收集的139 fb $^{-1}$数据寻找具有同号轻子和喷注的末态夸克和胶子

Search for squarks and gluinos in final states with same-sign leptons and jets using 139 fb$^{-1}$ of data collected with the ATLAS detector

ATLAS Collaboration

摘要:

寻找胶子和夸克的超对称伙伴,涉及的签名与喷流和两个孤立的轻子(电子或μ子)具有相同的电荷,或至少有三个孤立的轻子。质子-质子碰撞的数据样本在$\sqrt{s}$ = 13 TeV记录与ATLAS探测器在大型强子对撞机之间的2015年和2018年,对应于139 fb $^{-1}$的总积分亮度,用于搜索。未观察到显著超出标准模型预期的情况。结果被解释在简化的超对称模型具有R-宇称守恒和R-宇称违反,提高排除限制超出以前的ATLAS搜索到1600 GeV的胶子质量和750 GeV的底部和顶部夸克质量在这些情况下。

英文摘要:

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 $\sqrt{s}$ = 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.
