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.
