Exotic dynamically generated baryons with C$=-$1

TL;DR

This paper presents a model based on SU(8) symmetry that predicts exotic baryons with C=-1 by analyzing meson-baryon interactions, incorporating heavy quark symmetry and coupled-channel unitarity.

Contribution

It introduces a unified SU(8) symmetric framework for meson-baryon interactions, including vector mesons, to identify new baryonic resonances with exotic quantum numbers.

Findings

Identified poles in the T-matrix corresponding to exotic baryonic resonances.

Unified treatment of pseudo-scalar and vector mesons consistent with heavy quark symmetry.

Predicted new states with specific quantum numbers.

Abstract

We follow a model based on the SU(8) symmetry for the interaction of mesons with baryons. The model treats on an equal footing the pseudo-scalars and the vector mesons, as required by heavy quark symmetry. The T-matrix calculated within an unitary scheme in coupled channels has poles which are interpreted as baryonic resonances.
