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

Abstract

In this work we calculate the mass spectrum of strangeonium up to the 3D multiplet within a nonrelativ-istic linear potential quark model. Furthermore, using the obtained wave functions, we also evaluate the strong decays of the strangeonium states with the 3Pomodel. Based on our successful explanations of the well established states φ(1020), φ(1680), h1(1415), f′2(1525), and φ3(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 f2(2010) and f2(2150), 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 φ(2170) as a candidate for φ(35) or φ(2D) cannot be excluded. We expect our results to provide useful references for looking for the missing ss¯ states in future experiments.
