Probing charmonium-like state $X(3915)$ through meson photoproduction

Abstract

Inspired by the observation of charmonium-like state $X(3915)$, we explore the discovery potential of the $X(3915)$ production via meson photoproduction process. By investigating the $\gamma p\to J/\psi \omega p$ process including the $X(3915)$ signal and background contributions, we obtain the corresponding information of the cross section, the Dalitz plot and the $J/\psi \omega$ invariant mass spectrum, which is helpful to further experimental study of $X(3915)$ via meson photoproduction.
