Abstract

We present an analysis of axion-like particle (ALP) production in SUSY DFSZ-like model at the ILC and LHeC. We calculate the differential and total cross-sections in $\gamma^{*}e^{-}$ and $e^{-}e^{+}$ collisions including the effect of the scattering angle, the polarization coefficients, the energy and the ALP mass. From that, we compare the total cross-sections at the LHeC to those at the ILC. To predict the existence of ALP signals, we evaluate the significance level of the final state followed by ALP decaying di-photon at the LHeC and the ILC.
