论文摘要
标准模型中改变风味的中性电流相互作用会严重抑制，并且可以使用此类相互作用来搜索SM以外的新物理。顶级夸克和希格斯玻色子比SM中的其他颗粒重，我们可以预料新物理学在它们的相互作用中起着更重要的作用。在这项工作中，我们通过与14TEV上的Higgs Boson和100TEV $ PP $ Colleders的Higgs Boson相关的生产来研究顶级夸克$ \ bar {t} q H $之间的中性当前相互作用。我们考虑了希格斯的松弛衰减通道并研究信号。我们发现一个敏感区域$ 0.4 \leqΔr\ leq1.4 $，用于来自Higgs玻色子的瘦素，以及来自顶部夸克和瘦小的喷气机之间的$ΔR\ geq1.8 $。我们研究了该过程的强子山脉侦探能力。尽管此过程似乎与$ pp \ to t \ bar {t} $具有$ t \ to h q $衰减不可媲美，但它仍然很有吸引力，因为此过程可用于区分$ y_ {tu} $和$ y_ {tc} $。
The flavor-changing neutral current interactions in the standard model are suppressed seriously and such interactions can be used to search the new physics beyond SM. The top quark and Higgs bosons are heavier than the other particles in SM, we can expect the new physics plays a more important role in their interactions. In this work, we study the flavor-changing neutral current interactions between the top quark $\bar{t}q H$ through the production of the single top associated with a Higgs boson on 14TeV and 100TeV $pp$ colliders. We consider the leptonic decay channels of Higgs and study the signal. We find a sensitive region $0.4\leqΔR\leq1.4$ for the leptons from Higgs bosons and $ΔR\geq1.8$ between the jets from top quark and leptons. We investigate the detective abilities of the hadron colliders for the processes. Although this process seems not comparable with $pp\to t\bar{t}$ with $t\to H q$ decay, it is still attractive since this process can be used to distinguish the $y_{tu}$ and $y_{tc}$.
