Inspired by the observation of charmonium-like Z(4200), we explore the discovery potential of the neutral Z0(4200) production by antiproton-proton annihilation with an effective Lagrangian approach. By investigating the p-p→J/ψπ0 process including the Z0(4200) signal and background contributions, it is found that the center of mass energy Ec.m. ≃ 4.0–4.5 GeV is the best energy window for searching the neutral Z0(4200), where the signal can be clearly distinguished from background. The relevant calculations not only are helpful to search for the neutral Z0(4200) in the future experiment but also will promote the understanding of the nature and production mechanism of neutral Z0(4200) better.
