Hadronic resonances with exotic electric charge

Abstract

We classify the meson and baryon long lived resonances considering quarks with electric charge 5/3 and $-4/3$ (in units of $|e|$) predicted by some 3-3-1 models. Some of these exotic resonances have the usual electric charges $0,\pm 1$, 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.
