Abstract
In this paper, the excited states of the meson, especially containing the newly observed with by the BESIII Collaboration, is studied. In addition, as a meson excited state is investigated. The mass spectrum and strong decay behaviors of meson excited states are analyzed, which indicates that and are the candidates of and states with , respectively. In addition, and are predicted to have the mass of 1.87 and 2.5 GeV and width of 440 and 940 MeV, respectively.
