Abstract

Inserting the masses of some states, which have been established in theexperiments or the theory of lattice QCD, we investigate the mass of theisodoublet of the 23S1 meson nonet. The agreement results,1567±22.6 MeV and 1576.8 MeV, are given by two differentapproaches. We suggest that the assignment of 23S1 meson nonetshould be re-examined in future experiments.
