Kaon and Nucleon States with Hidden Charm

TL;DR

This paper predicts new exotic hadron states with hidden charm, including a mesonic state and baryonic states, generated through three-body interactions, expanding the understanding of hadron spectroscopy.

Contribution

It introduces a novel theoretical prediction of specific hidden charm states arising from three-body interactions in the strangeness and baryonic sectors.

Findings

Prediction of a $K^*(4307)$ mesonic state with mass ~4307 MeV.

Prediction of $N^*$ states with masses 4400-4600 MeV.

States have narrow widths of 2-20 MeV.

Abstract

In this talk we discuss the formation of exotic hadrons with hidden charm arising from three-body interactions. To be more specific, in the strangeness sector, we predict the existence of a mesonic state, $K^*(4307)$, which is dynamically generated from the three-body interactions of the $KD\bar{D}^*$ system, has mass around $4307$ MeV and quantum numbers $I(J^P) = 1/2\,(1^-)$. In the baryonic sector, we predict the existence of $N^*$ states, which are generated from the three-body interactions of the $ND\bar{D}^*$ system, with masses around $4400\sim 4600$ MeV, widths of $2\sim 20$ MeV and positive parity.
