Hidden charmed states and multibody color flux-tube dynamics

TL;DR

This paper explores hidden charmed states using a color flux-tube model with multibody confinement, proposing that many can be described as compact tetraquark states formed through a dynamical multibody mechanism.

Contribution

It introduces a multibody confinement potential in the color flux-tube model to systematically describe hidden charmed tetraquark states.

Findings

Most hidden charmed states can be modeled as compact tetraquarks.

Multibody confinement plays a key role in formation and decay.

The model aligns well with recent experimental observations.

Abstract

Within the framework of the color flux-tube model with a multibody confinement potential, we systematically investigate the hidden charmed states observed in recent years. It can be found that most of them can be described as the compact tetraquark states $[cq][\bar{c}\bar{q}]$ ($q=u,d$ and $s$) in the color flux-tube model. The multibody confinement potential based on the color flux-tube picture is a dynamical mechanism in the formation and decay of the compact tetraquark states.
