英文摘要	Inspired by the observation of the fully-charm tetraquark X(6900) state at LHCb, the production of X(6900) in (p) over barp -> J/psi J/psi reaction is studied within an effective Lagrangian approach and Breit-Wigner formula. The numerical results show that the cross section of X(6900) at the c.m. energy of 6.9 GeV is much larger than that from the background contribution. Moreover, we estimate dozens of signal events can be detected by the D0 experiment, which indicates that searching for the X(6900) via antiproton-proton scattering may be a very important and promising way. Therefore, related experiments are suggested to be carried out.
