Abstract

Mass distributions of pi⁺ pi^- pi⁰ and omega pi⁰ systems in the e⁺ e^- annihilation obtained by the several experiments are analyzed. We obtain indication of light-vector mesons omega'(1.3) and rho'(1.3) in the lower mass region. Those states are expected to exist in the U~(12)-classification scheme.
