Mass spectrum and strong decays of strangeonium in a constituent quark model *

In this work we calculate the mass spectrum of strangeonium up to the multiplet within a nonrelativistic linear potential quark model. Furthermore, using the obtained wave functions, we also evaluate the strong decays of the strangeonium states with the P-3(0) model. Based on our successful explanations of the well established states phi(1020), phi(1680), h(1)(1415), f(2)' (1525) and phi(3)(1850), we further discuss the possible assignments of strangeonium-like states from experiments by combining our theoretical results with observations. It is found that some resonances, such as and, listed by the Particle Data Group, and X(2062) and X(2500), newly observed by BESIII, may be interpreted as strangeonium states. The possibility of phi(2170) as a candidate for phi(3S) or phi(2D) cannot be excluded. We expect our results to provide useful references for looking for the missing s (s) over bar states in future experiments.
