Exotic states with triple charm

TL;DR

This paper predicts the existence of exotic triple-charm states formed from a three-body $D^*D^*D^*$ system, using Faddeev equations, revealing new multiquark hadrons with specific quantum numbers and masses.

Contribution

It introduces a novel theoretical prediction of exotic triple-charm states from three-body dynamics using the fixed center approximation.

Findings

Predicted $J^P=0^-$, $1^-$, $2^-$ states with charm 3.

States have isospin 1/2 and masses around 6000 MeV.

These states are manifestly exotic multiquark hadrons.

Abstract

In this work we investigate the possibility of the formation of states from the dynamics involved in the $D^*D^*D^*$ system by considering that two $D^*$'s generate a $J^P=1^+$ bound state, with isospin 0, which has been predicted in an earlier theoretical work. We solve the Faddeev equations for this system within the fixed center approximation and find the existence of $J^P=0^-$, $1^-$ and $2^-$ states with charm $3$, isospin $1/2$, masses $\sim 6000$ MeV, which are manifestly exotic hadrons, i.e., with a multiquark inner structure.
