Abstract

Abstract: We explore the signals of axion-like particles (ALPs) via the process e + e − → aγ → 3 γ 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.
