论文摘要
灵感来自LHCB的全面Tetraquark $ X（6900）$ State的启发，在有效的Lagrangian方法和Breteit-Wigner-Wigner-Wigner-Wigner Formula中研究了$ x（6900）$ in $ \ bar {p} p \ bar {p} p \ rightArrow J/ψJ/ψ$。数值结果表明，C.M. $ x（6900）$的横截面6.9 GEV的能量比背景贡献大得多。此外，我们可以通过D0实验检测到数十个信号事件，这表明通过抗Proton-Proton散射搜索$ x（6900）$可能是一种非常重要且有希望的方法。因此，建议进行相关的实验。
Inspired by the observation of the fully-charm tetraquark $X(6900)$ state at LHCb, the production of $X(6900)$ in $\bar{p}p\rightarrow J/ψJ/ψ$ 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 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.
