论文摘要
在标准模型（SM）以外的许多情况下出现的大量轨距多重的外来瘦素可以成对或结合在LHC上产生。由于它们的大量质量，最终的衰减产品（Sm Leptons and Bosons）往往会受到高度增强，而SM玻色子的喷射却更有可能表现为单个脂肪射流，而不是两个解决方案。随着相应的SM背景被抑制，预计具有两个或三个瘦素的最终状态和一个或两个脂肪射流对探测外来的费米子的敏感性比1 TEV重得多，我们提出并研究了适当的搜索策略。为了集中精力，我们考虑通过单一类型（三重态，四倍或Quintuplets）的Leptonic多重组进行SM的扩展，请记住，这种简化的模型通常会以更雄心勃勃的场景的低能限制出现，以解决SM SM的各种障碍。在13 TEV LHC上对9个此类场景进行系统，全面的研究，我们发现相应的$5σ$ Discovery的范围从985 GEV到1650 GEV到1650 GEV（1345 GEV至2020 GEV），300（3000）FB $^{ - 1} $。
Exotic leptons in large gauge multiplets, appearing in many scenarios beyond the Standard Model (SM), can be produced at the LHC in pairs or association. Owing to their large masses, their eventual decay products -- SM leptons and bosons -- tend to be highly boosted, with the jets stemming from the SM bosons more likely to manifest themselves as a single fat-jet rather than two resolved ones. With the corresponding SM backgrounds being suppressed, final states with two or three leptons and one or two fat-jets are expected to be sensitive in probing exotic fermions much heavier than 1 TeV, and we propose and investigate an appropriate search strategy. To concentrate on the essential, we consider extensions of the SM by leptonic multiplets of a single kind (triplets, quadruplets or quintuplets), bearing in mind that such simplified models typically arise as low-energy limits of more ambitious scenarios addressing various lacunae of the SM. Performing a systematic and comprehensive study of nine such scenarios at the 13 TeV LHC, we find that the corresponding $5σ$ discovery reaches a range from 985 GeV to 1650 GeV (1345 GeV to 2020 GeV) for 300 (3000) fb$^{-1}$.
