利用大型强子对撞机上的ATLAS探测器，以积分光度对应的数据样本，对13 TeV质子-质子碰撞中的类矢量夸克衰变为希格斯玻色子和顶夸克进行了研究。希格斯-玻色子和顶夸克候选粒子在全强子衰变模式下被识别，并被重建为大半径喷注。使用标记算法识别候选希格斯玻色子、顶夸克和关联强子。在背景上方没有观察到显著的过剩，因此对单夸克的产生截面设定了95%的置信度，这取决于矢量型夸克与标准模型粒子的质量和耦合。在所考虑的1.0到2.3TeV的质量范围内，允许的耦合值的上限从最小值0.35增加到1.6。
A search is made for a vectorlikequark decaying into a Higgs boson and a top quark in 13 TeV proton-proton collisions using the ATLAS detector at the Large Hadron Collider with a data sample corresponding to an integrated luminosity of. The Higgs-boson and top-quark candidates are identified in the all-hadronic decay mode, whereandare reconstructed as large-radius jets. The candidate Higgs boson, top quark, and associatedhadrons are identified using tagging algorithms. No significant excess is observed above the background, so limits are set on the production cross section of a singletquark at 95% confidence level, depending on the massand couplingof the vectorlikequark to Standard Model particles. In the considered mass range between 1.0 and 2.3 TeV, the upper limit on the allowed coupling values increases withfrom a minimum value of 0.35 forto 1.6 for.
