Abstract

The particle production in photon-photon ($\gamma \gamma$) interactions present in electron-ion collisions is investigated. We present calculations for the total cross sections and event rates related to the production of light mesons [$\eta, \eta^\prime, f_0$ and $f_2$], charmonium [$\eta_c$ and $\chi_c$] and charmoniumlike [$X(3915), X(3940), X(4140)$ and $X(6900)$] states, considering the EIC, EicC, LHeC and FCC-eh energies. Our predictions demonstrate that experimental studies of these processes are feasible and useful to constrain the properties of light mesons and quarkonium states and shed some light on the configuration of the considered charmoniumlike states.
