Description
We study the physics potentials of heavy QCD axions at 3/10 TeV muon colliders (MuC). These heavy QCD axions differ from typical ALPs as they solve the Strong CP puzzle, and their phenomenology is driven by the $aG\tilde{G}$ couplings. Different realizations of heavy QCD axions have different implications, and we show comprehensively how muon colliders can uniquely probe them with a huge parameter space. Additionally, we find a set of vector-boson-scattering channels at MuC that dominate the axion production rate rather than the usual vector-boson-fusion channel.
