Production of axion-like particles via vector boson fusion at future electron-positron colliders

Abstract

One kind of particularly interesting pseudoscalar particles, called axion-like particles (ALPs), have rich physical phenomenology at high- and low-energy collider experiments. After discussing most of single production channels of ALP at electron-positron colliders, we investigate the possibility of detecting this kind of new particles through the W${}^{+}$W${}^{-}$ fusion process e${}^{+}$e${}^{-}$ $\to$ ${\overline{\nu }}_e$${\nu }_{e}a$ $(\to \gamma \gamma )$ at the CLIC. The 3$\sigma$ and 5$\sigma$ bounds on the ALP parameter space at the three energy stages of the CLIC are obtained. We find that the bounds given by the CLIC are complementary to the existing experiments exclusion regions.
