Prediction of narrow $N^{*}$ and $\Lambda^*$ resonances with hidden charm above 4 GeV

TL;DR

This paper predicts new narrow hidden-charm baryon resonances above 4 GeV using a coupled channel approach, suggesting they cannot be explained by traditional quark models and are testable at upcoming experiments.

Contribution

It introduces a novel prediction of narrow hidden-charm $N^*$ and $\\Lambda^*$ resonances with masses above 4 GeV using the coupled channel unitary approach with hidden gauge formalism.

Findings

Predicted narrow resonances with widths less than 100 MeV

Resonances cannot be explained by three-quark models

Potential observation at PANDA/FAIR experiments

Abstract

The interaction between various charmed mesons and charmed baryons are studied within the framework of the coupled channel unitary approach with the local hidden gauge formalism. Several meson-baryon dynamically generated narrow $N^*$ and $\Lambda^*$ resonances with hidden charm are predicted with mass above 4 GeV and width smaller than 100 MeV. The predicted new resonances definitely cannot be accommodated by quark models with three constituent quarks and can be looked for at the forthcoming PANDA/FAIR experiments.
