Is an axizilla possible for di-photon resonance?

Understand

Heavy axion-like particles, called axizillas, are simple extensions of the standard model(SM).

• An axizilla is required not to couple to the quarks, leptons, and Brout-Englert-Higgs doublets of the SM, but couple to the gauge anomalies of the $W^\pm, Z$ and photon.
• It is possible to have its branching ratios(BRs) to two photons greater than 10% and to two $Z$'s less than 10%.
• To have a (production cross section)$\cdot $(BR to di-photons) at a $10^{-38}\,\textrm{cm}^2$ level, a TeV scale heavy quark $Q$ is required for the gluon--quark fusion process.
