The decay widths for the nucleon to an antilepton and a photon are not so well bounded experimentally as $\\ell \\pi$ modes. Using an effective Lagrangian approach, we relate the decay widths of $N\\to \\ell \\gamma $ to the decay widths of $N\\to \\ell \\pi$. Our result points out factor $10^{3}$ suppression of the decay widths $\\Gamma (p \\to \\ell^{+} \\gamma)$ and $\\Gamma (n \\to \\bar \\nu \\gamma)$ compared to the decay widths $\\Gamma (p \\to \\ell^{+} \\pi^{0})$ and $\\Gamma (n \\to \\bar \\nu \\pi^{0})$, res"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2304.00825","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":""},"integrity":{"clean":true,"summary":{"advisory":0,"critical":0,"by_detector":{},"informational":0},"endpoint":"/pith/2304.00825/integrity.json","findings":[],"available":true,"detectors_run":[],"snapshot_sha256":"c28c3603d3b5d939e8dc4c7e95fa8dfce3d595e45f758748cecf8e644a296938"},"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"}
