摘要

We investigate the mass spectrum of the ss(s)(s) tetraquark states in the relativized quark model.By solving the Schr(o)dinger-like equation with the relativized potential,the masses of S-and P-wave ss(s)(s) tetraquarks are obtained.The screening effects are also taken into account.It is found that the resonant structure X(2239) observed in the e+e-→ K+K-process by the BESⅢ collaboration can be assigned as a P-wave 1--ss(s)(s) tetraquark state.Furthermore,the radiative transition and the strong decay behavior of this structure are also estimated,which can provide helpful information for future experimental searches.
