Abstract

Inspired by the observation of charmoniumlike state $X (3915)$ , we explore the discovery potential of the $X (3915)$ production via meson photoproduction process. By investigating the $γ p \to J / ψ ω p$ process including the $X (3915)$ signal and background contributions, we obtain the corresponding information of the cross section, the Dalitz plot, and the $J / ψ ω$ invariant mass spectrum, which are helpful in further experimental study of $X (3915)$ via meson photoproduction.
