abstract
We determine the model-independent component of the couplings of axions to electroweak gauge bosons, induced by the minimal coupling to QCD inherent to solving the strong CP problem. The case of the invisible QCD axion is developed first, and the impact on $W$ and $Z$ axion couplings is discussed. The analysis is extended next to the generic framework of heavy true axions and low axion scales, corresponding to scenarios with enlarged confining sector. The mass dependence of the coupling of heavy axions to photons, $W$ and $Z$ bosons is determined. Furthermore, we perform a two-coupling-at-a-time phenomenological study where the gluonic coupling together with individual gauge boson couplings are considered. In this way, the regions excluded by experimental data for the axion-$WW$, axion-$ZZ$ and axion-$Z\gamma$ couplings are determined and analyzed together with the usual photonic ones. The phenomenological results apply as well to ALPs which have anomalous couplings to both QCD and the electroweak bosons.

ALP pair production at the LHC
Non-resonant gg→aa→4γ production could constrain the dimension-6 ALP-gluon coupling down to ~10^-3 TeV^-2 at 300 fb^-1, but the allowed parameter space remains unbounded along multiple flat directions.

Searching for long-lived ALPs with a laser-assisted optical dump
A laser-assisted optical dump could probe ALP-electron couplings down to ~10^-6 (10^-7) GeV^-1 with 16.5 (125) GeV electron beams, and when both couplings are present the Primakoff process improves the electron-coupli...

CP Polarimetry with Linearly Polarized Photon Fusion and Double-Tagged Protons
The CP-mixing angle of a photon-coupled spin-zero resonance shifts the second harmonic in the azimuthal angle between the two tagged protons, enabling a decay-analyzer-independent CP measurement.

New axion contribution to the two-photon decays of neutral pions
Axion-pion mixing adds a new next-to-leading-order term to the pi0 to gamma gamma decay width that is negligible for standard light axions but may matter for MeV-scale heavy axions.
