Rescattering by $\\overline{K^*}K+K^*\\overline{K}$ and $\\rho^{+}\\rho^{-}$ for $\\overline{p}p\\rightarrow\\pi\\phi$ states is sizable, of order $(0.90\\, {\\rm to}\\,2.6)\\times 10^{-4}$ in the branching ratio, but smaller than experiment. For $\\overline{p}p\\rightarrow\\gamma\\phi$ the rescattering contributions are negligible, but the $\\gamma\\phi$ channel is well explained by a $\\rho\\phi$ intermediate state combined with vector meson dominance."},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"nucl-th/9311021","kind":"arxiv","version":1},"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"}
