3 + + light meson family

Year: 2026

Type: article

Abstract: The spectroscopy of the 3 + + light-meson candidates, in particular the a 3 and f 3 families, remains an open issue. We compute the mass spectra in the modified Godfrey-Isgur model and evaluate the Okubo-Zweig-Iizuka-allowed two-body strong decays within the quark-pair-creation model. Our analysis favors the interpretation that a 3 ( 1875 ) and a 3 ( 2030 ) correspond to the same resonance, identified as the a 3 ground state, while f 3 ( 2050 ) is the ground state of the f 3 family; furthermore, a 3 ( 2275 ) and f 3 ( 2300 ) are assigned as their first radial excited states. For other higher-excitation states, we provide predictions for the decay behaviors and include the mass-induced model uncertainty.
