Our calculation indicates there exist a sharp peak structure ($Z_{s1}^+$) close to the $K\\bar{K}^\\ast$ threshold and a broad structure ($Z_{s2}^+$) near the $K^\\ast\\bar{K}^\\ast$ threshold. In addition, we also investigate the $\\phi(1680) \\to \\phi(1020)\\pi^{+} \\pi^{-}$ process due to the ISPE mechanism, where a sharp peak around the $K\\bar{K}^\\ast$ threshold appears in the $\\phi(1020)\\pi^{+}$ invariant mass spectrum distribution"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1112.3773","kind":"arxiv","version":3},"verdict":{"id":null,"model_set":{},"created_at":null,"strongest_claim":"","one_line_summary":"","pipeline_version":null,"weakest_assumption":"","pith_extraction_headline":""},"references":{"count":0,"sample":[],"resolved_work":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57","internal_anchors":0},"formal_canon":{"evidence_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"author_claims":{"count":0,"strong_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"builder_version":"pith-number-builder-2026-05-17-v1"}
