Experimental Indication of Existence of Extra Light-Vector Mesons omega'(1.3) and rho'(1.3)
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.
