Dynamically generated $N^{*}$ and $\Lambda^*$ resonances in the hidden charm sector around 4.3 GeV

TL;DR

This paper predicts new narrow $N^*$ and $\\Lambda^*$ resonances around 4.3 GeV in the hidden charm sector using a coupled channel approach, and estimates their production in proton-antiproton collisions for future experiments.

Contribution

It introduces a novel prediction of hidden charm resonances through a coupled channel unitary approach with local hidden gauge formalism.

Findings

Predicted narrow $N^*$ and $\Lambda^*$ resonances around 4.3 GeV.

Estimated production cross sections for these resonances in $\bar{p} p$ collisions.

Resonances are dynamically generated from meson-baryon interactions.

Abstract

The interactions of $\bar{D}\Sigma_{c}$-$\bar D\Lambda_c$, $\bar{D}^{*}\Sigma_{c}$-$\bar D^*\Lambda_c$, and related strangeness channels, are studied within the framework of the coupled channel unitary approach with the local hidden gauge formalism. A series of meson-baryon dynamically generated relatively narrow $N^*$ and $\Lambda^*$ resonances are predicted around 4.3 GeV in the hidden charm sector. We make estimates of production cross sections of these predicted resonances in $\bar{p} p $ collisions for PANDA at the forthcoming FAIR facility.
