Hadronic resonances with exotic electric charge

TL;DR

This paper classifies long-lived hadronic resonances with exotic electric charges predicted by 3-3-1 models, introducing a new symmetry to organize these exotic states and analyzing their decay properties.

Contribution

It introduces a classification scheme for exotic hadronic resonances with unusual charges and proposes a new heavy $SU(3)_H$ symmetry to organize states involving exotic quarks.

Findings

Exotic resonances with charges up to ±5 are identified.

Some resonances decay only into leptons and known particles.

A new symmetry framework is proposed for exotic hadron classification.

Abstract

We classify the meson and baryon long lived resonances considering quarks with electric charge 5/3 and $-4/3$ (in units of $\vert e\vert$) predicted by some 3-3-1 models. Some of these exotic resonances have the usual electric charges $0,\pm1$, others have $\pm(3,4,5)$, and the lightest ones decaying only into leptons plus known resonances. We propose another heavy $SU(3)_H$ global symmetry under which hadrons involving only exotic quarks can be constructed.
