With these form factors, we calculate the decay branching ratios of all possible modes for $V\\to P\\ell^+\\ell^-$ ($V=\\omega$ and $\\phi$, $P=\\pi^0$, $\\eta$ and $\\eta^{\\prime}$ and $\\ell=e$ and $\\mu$). We find that our numerical results fit with the data, such as those of $\\omega \\to \\pi^0 \\ell^+\\ell^-$ and $\\phi\\to \\pi^0 e^+e^-$ by NA60 and $\\phi \\to\\eta e^+e^-$ by SND. We also predict that the branching ratios of $\\phi \\to \\pi^0 \\mu^+\\mu"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1406.2095","kind":"arxiv","version":2},"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"}
