论文摘要
我们讨论了$ j \！/\！ψ\，j \！/\！ψ$ peacs最近在CERN看到的，并借此机会回顾了异国情调的Hadron的实验和理论状态。有人强调，在组成模型中，连续体中的状态需要专门的治疗，才能在连续体的顶部单一结合共振。
We discuss the interpretation of the $J\!/\!ψ\,J\!/\!ψ$ peak recently seen by the LHCb collaboration at CERN, and take the opportunity to review the experimental and theoretical state of the art for exotic hadrons. It is stressed that in constituent models, the states in the continuum require a dedicated treatment to single out resonances atop the continuum.
