摘要：

Via the Initial Single Pion Emission (ISPE) mechanism, we study the phi(1020)pi(+) invariant mass spectrum distribution of Y(2175) -> phi(1020)pi(+)pi(-). Our calculation indicates there exist a sharp peak structure (Z(s1)(+)) close to the K (K) over bar* threshold and a broad structure (Z(s2)(+)) near the K*(K) over bar* threshold. In addition, we also investigate the phi(1680) -> phi(1020)pi(+)pi(-) process due to the ISPE mechanism, where a sharp peak around the K (K) over bar* threshold appears in the phi(1020)pi(+) invariant mass spectrum distribution. We suggest to carry out the search for these charged strangeonium-like structures in future experiments, especially Belle II, Super-B and BESIII.
