论文摘要
搜索使用139 fb $^{ - 1} $ $ \ sqrt {s} = 13 $ tev $ pp $碰撞数据的搜索具有较大影响参数的带电瘦素，从LHC的地图集检测器出现了碰撞数据，这列出了长期存在的差距，以覆盖可能的新物理学签名。结果与背景预测一致。该搜索对长寿命标量超对称Lepton-Partners（Sleptons）提供了独特的敏感性。对于0.1 ns的寿命，Selectron，Smuon和Stau质量分别以95％的置信度排除了高达720 GEV，680 GEV和340 GEV，从而在LEP先前的最佳限制上大幅提高了LEP的置信度。
A search for charged leptons with large impact parameters using 139 fb$^{-1}$ of $\sqrt{s} = 13$ TeV $pp$ collision data from the ATLAS detector at the LHC is presented, addressing a long-standing gap in coverage of possible new physics signatures. Results are consistent with the background prediction. This search provides unique sensitivity to long-lived scalar supersymmetric lepton-partners (sleptons). For lifetimes of 0.1 ns, selectron, smuon and stau masses up to 720 GeV, 680 GeV, and 340 GeV are respectively excluded at 95% confidence level, drastically improving on the previous best limits from LEP.
