Up to our accuracy, the effect of the momentum dependence of $\\rho-\\omega$ mixing is incorporated due to the inclusion of loop contributions. We analyze the impact of $\\rho-\\omega$ mixing on the pion vector form factor by performing numerical fit to the data extracted from $e^+e^-\\rightarrow \\pi^+\\pi^-$ and $\\tau\\rightarrow \\nu_{\\tau}2\\pi$, while the decay width of $\\omega\\rightarrow \\pi^+\\pi^-$ is ta"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1710.11448","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"}
