摘要

Inspired by the observation of charmonium-likeZ(4200), we explore the discovery potential of the neutralZ0(4200)production by antiproton-proton annihilation with an effective Lagrangian approach. By investigating thep-p→J/ψπ0process including theZ0(4200)signal and background contributions, it is found that the center of mass energyEc.m.≃4.0–4.5 GeV is the best energy window for searching the neutralZ0(4200), where the signal can be clearly distinguished from background. The relevant calculations not only are helpful to search for the neutralZ0(4200)in the future experiment but also will promote the understanding of the nature and production mechanism of neutralZ0(4200)better.
