寻找强产生的超对称粒子是使用涉及多个高能喷流和两个具有相同电荷的孤立轻子（e或μ）或至少三个孤立轻子的签名进行的。该搜索还利用源自b夸克的喷流，缺少横向动量和其他可观测量来扩展其灵敏度。该分析使用的数据样本对应于2012年在大型强子对撞机上使用ATLAS探测器记录的TeX = 8 TeV质子-质子碰撞的总积分光度为20.3 fb。未观察到与标准模型预期的偏离。新的或显着改进的排除限制设置在各种各样的超对称模型，其中最轻的squark可以是第一，第二或第三代，并在其中R-奇偶校验可以保存或违反。
A search for strongly produced supersymmetric particles is conducted using signatures involving multiple energetic jets and either two isolated leptons (e or μ) with the same electric charge, or at least three isolated leptons. The search also utilises jets originating from b-quarks, missing transverse momentum and other observables to extend its sensitivity. The analysis uses a data sample corresponding to a total integrated luminosity of 20.3 fb‾¹ of TeX = 8 TeV proton-proton collisions recorded with the ATLAS detector at the Large Hadron Collider in 2012. No deviation from the Standard Model expectation is observed. New or significantly improved exclusion limits are set on a wide variety of supersymmetric models in which the lightest squark can be of the first, second or third generations, and in which R-parity can be conserved or violated.
