The q anti-q wave functions found for mesons and photon lead to a reasonably good description of data ($\\Gamma^{(exp)}_{\\rho^{\\pm} \\to\\gamma\\pi^{\\pm}}=68\\pm 30$ keV, $\\Gamma^{(exp)}_{\\rho^{0}\\to\\gamma\\pi^0}=77\\pm 28$ keV, $\\Gamma^{(exp)}_{\\omega\\to\\gamma\\pi^0}=776\\pm 45$ keV) that makes it possible to estimate the coupling for the bremsstrahlung emission "},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"0901.4854","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"}
