“…Certainly, the couplings of ALP to fermions are well-motivated in some cases. Recent searches for the ALP induced by the ALP-fermion couplings have been proposed [36][37][38]. The model file is generated by FeynRules [39].…”

We explore the signals of axion-like particles (ALPs) via the process e + e − → aγ → 3γ at the Circular Electron Positron Collider (CEPC). The expected sensitivities of the CEPC with the center of mass energy s = 240 GeV for the ALP parameter space are obtained. Our results show that the promising sensitivities of the CEPC to the coupling g aγγ are in the range of 3.25 × 10−5 GeV−1 to 3.7 × 10−4 GeV−1 with the ALP mass m a from 2.9 GeV to 190 GeV.
