abstract
We present a consistent derivation of the complete Wess-Zumino-Witten interactions of axions, including the counter-term necessary to guarantee the gauge invariance of the Standard Model. By treating the derivative of the axion field as a background gauge field and incorporating auxiliary chiral rotation phases, we ensure consistency in the axion-interaction Lagrangian. This approach allows us to derive basis-independent physical interactions of axions with gauge bosons and vector mesons. As an example, we explore the interaction of $a$-$\omega$-$\gamma$ to illustrate the potential for searching for axion-like particles at colliders.

A covariant framework identifies redefinition-invariant ALP couplings to gluons and quarks and computes physical decay rates for mixed scenarios.
A matching framework from arbitrary KSVZ UV completions to SMEFT and ALP EFT yields robust operator bounds from global fits that often dominate direct ALP searches except when mass mixing occurs.
A phenomenological 2-to-3 framework is constructed for exclusive boson electroproduction that matches flux-factorized predictions near Q^{2}=0 while capturing finite-Q^{2} effects at larger virtualities.
The EIC can probe invisible pseudoscalar meson decays down to branching ratios of 10^{-8} and invisibly decaying ALPs with couplings up to 10^5 GeV for masses 0.1-2 GeV.
