六次早期运行 2 ATLAS 搜索超对称性的组合约束在标准模型 (pMSSM) 的现象学最小超对称扩展中进行了解释。每次搜索均基于 2015 年在 $\sqrt{s} =13$ TeV 处记录的质子-质子碰撞数据，积分光度为 3.2 fb$^{-1}$。使用快速探测器模拟评估对前两代夸克和胶子的敏感性。结果呈现在 19 参数 R 宇称守恒 pMSSM 中，其中最轻的超对称粒子 (LSP) 是中性子。考虑到 181.8k 点在运行 1 约束下幸存下来，15.7% 在 95% 置信水平下被排除。在满足这些运行 2 约束的物质中，0.5% (1.0%) 具有亚 TeV 胶子（亚 500 GeV 夸克），其中最轻的质量为 757 GeV (293 GeV)，LSP 为 689 GeV (217 GeV)。
The combined constraints from six early Run 2 ATLAS searches for supersymmetry are interpreted in the phenomenological minimal supersymmetric extension to the Standard Model (pMSSM). Each of the searches was based on proton-proton collision data recorded in 2015 at $\sqrt{s} =13$ TeV with 3.2 fb$^{-1}$ of integrated luminosity. Sensitivity to squarks of the first two generations and gluinos are evaluated using fast detector simulation. Results are presented in the 19-parameter R-parity conserving pMSSM with the lightest supersymmetric particle (LSP) being the neutralino. Considering 181.8k points that survived Run 1 constraints, 15.7% are excluded at 95% confidence level. Of those satisfying these Run 2 constraints, 0.5% (1.0%) have sub-TeV gluinos (sub-500 GeV squarks), the lightest of which has a mass of 757 GeV (293 GeV) with a 689 GeV (217 GeV) LSP.
