The four intermediate states contribute to this process: $\\omega\\eta$, $\\phi\\eta$, $a_0(980)\\rho$, and a structureless $\\pi^+\\pi^-\\pi^0\\eta$ state. We measure the total $e^+e^- \\to \\pi^+\\pi^-\\pi^0\\eta$ cross section and the cross sections for its components: $\\omega\\eta$, $\\phi\\eta$, and a sum of $a_0(980)\\rho$ and the structureless state. Our results are in agreement with previous measurements and have comparable or better accuracies"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1903.09307","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"}
