| 英文摘要 | Basing on the observation of a new J(PC) = 0(-+) state, X(2500), in the partial wave analysis of the decay J/psi -> gamma X -> gamma phi phi performed by the BESIII Collaboration, we have evaluated the strong decays of the X(2500) as the 4(1)S(0) and 5(1)S(0) s (s) over bar states in the P-3(0) model of meson decay. The predicted total decay width for the 4(1)S(0) (s) over bars is about 894.5MeV, and the one for the 5(1)S(0) (s) over bars is about 271.1 MeV, which is in agreement with the experimental data Gamma X(2500) = 230(-35-33)(+64+56) MeV. By considering the mass and the total strong decay width of the X(2500), we propose that the X(2500) state can be interpreted as a candidate of the 5(1)S(0) (s) over bars state. |
