寻找夸克和胶子（方和胶子）在含有强子喷流和失踪的横向动量，但没有电子或μ子的最终状态的超对称合作伙伴，提出。这次搜索中使用的数据是在2015年和2016年由ATLAS实验在大型强子对撞机上记录的质子-质子碰撞，对应的积分光度为。这些结果被解释在各种模型的背景下，方子和胶子是成对产生的，中性伴子是最轻的超对称粒子。假设最轻的中性伴子是无质量的，在95%的置信水平下，对于一个只包含一个胶子和最轻的中性伴子的简化模型，胶子质量的排除极限被设定为2.03 TeV。对于一个简化的模型，涉及到强大的生产质量简并的第一代和第二代squark，低于1.55 TeV的squark质量被排除在外，如果最轻的中性伴子是无质量的。这些限制大大扩展了超对称参数空间的区域，以前排除了搜索与ATLAS检测器。
A search for the supersymmetric partners of quarks and gluons (squarks and gluinos) in final states containing hadronic jets and missing transverse momentum, but no electrons or muons, is presented. The data used in this search were recorded in 2015 and 2016 by the ATLAS experiment inproton-proton collisions at the Large Hadron Collider, corresponding to an integrated luminosity of. The results are interpreted in the context of various models where squarks and gluinos are pair produced and the neutralino is the lightest supersymmetric particle. An exclusion limit at the 95% confidence level on the mass of the gluino is set at 2.03 TeV for a simplified model incorporating only a gluino and the lightest neutralino, assuming the lightest neutralino is massless. For a simplified model involving the strong production of mass-degenerate first- and second-generation squarks, squark masses below 1.55 TeV are excluded if the lightest neutralino is massless. These limits substantially extend the region of supersymmetric parameter space previously excluded by searches with the ATLAS detector.
