标题： Exploring Axion-Like Particle Couplings through Single Top $tW$-Channel and Top Pair Production at the LHC

摘要： 在本文中，我们探讨了光轴子类似粒子（ALPs）与顶夸克、胶子和W玻色子之间的相互作用。利用大型强子对撞机（LHC）的高能探测器，我们在伴随W玻色子和ALP的单顶夸克产生背景下研究这些耦合。我们分析最新的LHC运行二期数据中的$t\bar{t}$自旋相关性测量，以建立对这些耦合的限制。此外，我们将这些限制与来自环诱导耦合和涉及B介子衰变的间接搜索所得的限制进行比较。而且，我们推导出ALP与顶夸克和胶子耦合的二维限制。 显示英文摘要

摘要： In this paper, we explore the interactions between light axion-like particles (ALPs) and top quarks, gluons, and W-bosons. Utilizing high-energy probes at the LHC, we probe these couplings in the context of single top quark production associated with a W-boson and an ALP. We analyze the latest LHC Run II data on $t\bar{t}$ spin correlation measurements to establish constraints on these couplings. Additionally, we compare these constraints with those derived from loop-induced couplings and indirect searches involving B-meson decays. Furthermore, we derive two-dimensional limits on the ALP couplings with top quarks and gluons.
