关于LHCb的$J\!/\!ψ\,J\!/\!ψ$峰:全粲四夸克态?

About the $J\!/\!ψ\,J\!/\!ψ$ peak of LHCb: fully-charmed tetraquark?

Jean-Marc Richard

摘要:

我们讨论的解释最近看到的$J\!/\!ψ\,J\!/\!ψ$峰的LHCb合作在欧洲核子研究中心,并借此机会审查的实验和理论状态的艺术奇异强子。强调的是,在组分模型中,连续统中的状态需要专门的处理,以挑选出连续统顶部的共振。

英文摘要:

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.
