In this work we calculate the mass spectrum of strangeonium up to the $ 3D $ 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 $ ^3P_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 $ f_2(2010) $ and $ f_2(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 $ \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\bar{s} $ states in future experiments.

成分夸克模型中铷的质谱和强衰变 国家自然科学基金项目 (U1832173, 11775078, 11705056, 11405053)

$ 3D $在这项工作中,我们计算了非相对论线性势夸克模型中奇异元素的质谱直至多重峰。此外,使用获得的波函数,我们还用模型评估了奇异态的强衰变$ ^3P_0 $。基于我们对已确立的状态$ \phi(1020) $$ \phi(1680) $$ h_1(1415) $$ f'_2(1525) $和的成功解释$ \phi_3(1850) $,我们通过将我们的理论结果与观察结果相结合,进一步讨论了实验中可能的类奇异态分配。发现一些共振,例如粒子数据组列出的 和 ,$ f_2(2010) $以及BESIII 新观察到的和,可能被解释为奇鎓态。的可能性$ f_2(2150) $$ X(2062) $$ X(2500) $$ \phi(2170) $作为候选人$ \phi(3S) $$ \phi(2D) $不能被排除在外。$ s\bar{s} $我们希望我们的结果为在未来的实验中寻找缺失状态提供有用的参考。
