Search for axion-like particles with electron and positron beams at KEK Linac

Abstract

We propose a fixed-target experiment to search for Axion-like particles (ALPs) coupling to photons, which utilizes electron and positron beams available at KEK Linac. The sensitivity to ALP is evaluated for two shielding setups in conjunction with other beam dump experiments, fixed-target experiments, and $e^{+}{e}^{-}$ collider experiments. This study shows that the two setups can explore the gap between the search region excluded by the beam dump experiments and the $e^{+}{e}^{-}$ collider experiments.
