New constraints on axion-like particles at colliders

Axion-like particles (ALPs) appear in several well-motivated
extensions of the Standard Model. In this talk, we will discuss collider
constraints on axion-like particles. We will focus on bounds coming from the
so-called ALP-SMEFT interference, which relates the Wilson coefficients of
the ALP effective field theory to those of the Standard Model effective
field theory (SMEFT). Moreover, we will review limits on the couplings of
ALPs to the top quark.
