论文摘要
搜索至少一个孤立的Lepton（$ E $或$μ$）和两次喷气式的事件的搜索，并使用$ 139 \，{\ text {fb}}}^{ - 1} $ of $ \ sqrt {s} = 13 $ tev proton-proton Proton碰撞数据记录了由Atlas detector进行的。与平滑跌落的背景假设的偏差在三体和四体不变的质量分布中进行了测试，这些质量分布由瘦素和喷气机构成，包括从底部夸克（Bottom Quarks）识别的喷气机。介绍了最终状态下导致多个喷气机和瘦素的粒子的级联反应的模型无关的限制。限制是使用不变质量宽度不同的高斯形状计算的。多体不变质量还用于在生产的横截面时间分支比率上设置95％置信度的上限，并通过几种新物理场景预测的共振和随后的衰减。
A search for resonances in events with at least one isolated lepton ($e$ or $μ$) and two jets is performed using $139 \, {\text{fb}}^{-1}$ of $\sqrt{s}=13$ TeV proton-proton collision data recorded by the ATLAS detector at the LHC. Deviations from a smoothly falling background hypothesis are tested in three- and four-body invariant mass distributions constructed from leptons and jets, including jets identified as originating from bottom quarks. Model-independent limits on generic resonances characterised by cascade decays of particles leading to multiple jets and leptons in the final state are presented. The limits are calculated using Gaussian shapes with different widths for the invariant masses. The multi-body invariant masses are also used to set 95% confidence level upper limits on the cross-section times branching ratios for the production and subsequent decay of resonances predicted by several new physics scenarios
