Abstract

One of the main goals of future electron-ion colliders is to improve our understanding of the structure of hadrons. We study the exclusive ηc production by γγ* interactions in eA collisions and demonstrate that future experimental analysis of this process can be used to improve the description of the transition form factor. The rapidity, transverse momentum, and photon virtuality distributions are estimated considering the energy and target configurations expected to be present at the EIC, EicC, and LHeC and assuming different predictions for the light-front wave function of the meson. Our results indicate that electron-ion colliders can be considered an alternative for providing supplementary data to those obtained in colliders.
