论文摘要
在寻找新物理现象的签名时,研究了来自质子 - 普罗顿碰撞中的事件的数据样本,以及两个孤立的同符号或三个或三个或更多带电的瘦素的数据样本。该数据对应于137 fb $^{ - 1} $的集成发光度,在LHC的CMS实验在2016 - 2018年收集的13个TEV中心能量。使用多个运动学变量定义的总共168个信号区域进行搜索。事件的属性被发现与标准模型过程的期望一致。在95%的置信度下的排除限制设定在横截面上,用于在保存或违反r平价的超对称模型的背景下为各种衰减场景的gluinos或squarks的产生。观察到的较低的质量限制为Gluinos的2.1 TEV,顶部和底部的质量为0.9 TEV。为了促进重新解释,在一组简化的信号区域中提供了独立于模型的限制。
A data sample of events from proton-proton collisions with at least two jets, and two isolated same-sign or three or more charged leptons, is studied in a search for signatures of new physics phenomena. The data correspond to an integrated luminosity of 137 fb$^{-1}$ at a center-of-mass energy of 13 TeV, collected in 2016-2018 by the CMS experiment at the LHC. The search is performed using a total of 168 signal regions defined using several kinematic variables. The properties of the events are found to be consistent with the expectations from standard model processes. Exclusion limits at 95% confidence level are set on cross sections for the pair production of gluinos or squarks for various decay scenarios in the context of supersymmetric models conserving or violating R parity. The observed lower mass limits are as large as 2.1 TeV for gluinos and 0.9 TeV for top and bottom squarks. To facilitate reinterpretations, model-independent limits are provided in a set of simplified signal regions.
