Abstract

The spectroscopy of the 3++ light-meson candidates, in particular the a3 and f3 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 a3(1875) and a3(2030) correspond to the same resonance, identified as the a3 ground state, while f3(2050) is the ground state of the f3 family; furthermore, a3(2275) and f3(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.
