论文摘要
在最终的状态中，搜索夸克和胶子（squarks and gluinos）的超对称伴侣，其中包含喷气机和缺失的横向动量，但没有任何电子或muons。该搜索中使用的数据是由Atlas实验在质子 - 蛋白碰撞中记录的，以$ \ sqrt {s} $ = 13 tev在大型强子对撞机的运行2期间，对应于139 fb $^{ - 1} $。结果是在各种$ r $ parity的模型的背景下解释的，在这些模型中，挤压和gluinos成对或关联产生，中inino是最轻的超对称粒子。对于仅包含Gluino和最轻的中性诺的简化模型，Gluino质量的95％置信度的排除极限设置为2.30 TEV，假设后者是无质量的。对于涉及质量分级第一和第二代quark的强大产生的简化模型，如果最轻的中性诺无质量，则排除了低于1.85 TEV的挤压质量。这些限制大大延伸了超对称参数空间的区域，该空间先前与ATLAS检测器的类似搜索所排除。
A search for the supersymmetric partners of quarks and gluons (squarks and gluinos) in final states containing jets and missing transverse momentum, but no electrons or muons, is presented. The data used in this search were recorded by the ATLAS experiment in proton-proton collisions at a centre-of-mass energy of $\sqrt{s}$ = 13 TeV during Run 2 of the Large Hadron Collider, corresponding to an integrated luminosity of 139 fb$^{-1}$. The results are interpreted in the context of various $R$-parity-conserving models where squarks and gluinos are produced in pairs or in association and a neutralino is the lightest supersymmetric particle. An exclusion limit at the 95% confidence level on the mass of the gluino is set at 2.30 TeV for a simplified model containing only a gluino and the lightest neutralino, assuming the latter is massless. For a simplified model involving the strong production of mass-degenerate first- and second-generation squarks, squark masses below 1.85 TeV are excluded if the lightest neutralino is massless. These limits extend substantially beyond the region of supersymmetric parameter space excluded previously by similar searches with the ATLAS detector.
