Abstract
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±,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)⋅(BR to di-photons) at a 10−38cm2 level, a TeV scale heavy quark Q is required for the gluon--quark fusion process. The decay of Q to axizilla plus quark, and the subsequent decay of the axizilla to two photons can be fitted at the required level of 10−38cm2. ©2016 The Author. Published by Elsevier B.V.
