利用大型强子对撞机上的CMS探测器在质量能量为8TeV的质心能量下收集的19.4TeV或19.7TeV积分光度的数据样本，给出了搜索完全强子终态中的第三代夸克的数据样本。提出了三个互斥搜索，每个搜索都针对不同的衰减拓扑进行了优化。它们包括需要一个完全重建的顶夸克的多喷流搜索，需要一个或两个源自b夸克的喷流的双喷流搜索，以及单喷流搜索。没有看到超过标准模型预期的过度，在超对称简化模型的背景下，对顶夸克和底夸克的产生设定了限制。
Searches for third-generation squarks in fully hadronic final states are presented using data samples corresponding to integrated luminosities of 19.4 or 19.7 fb− 1, collected at a centre-of-mass energy of 8 TeV with the CMS detector at the LHC. Three mutually exclusive searches are presented, each optimized for a different decay topology. They include a multijet search requiring one fully reconstructed top quark, a dijet search requiring one or two jets originating from b quarks, and a monojet search. No excesses above the standard model expectations are seen, and limits are set on top and bottom squark production in the context of simplified models of supersymmetry.
