By assuming that a nonvanishing $Z\\gamma \\gamma$ vertex is induced in some context of new physics, and by analyzing the reaction $H\\to \\gamma Z^*\\to \\gamma \\gamma \\gamma$ in the $Z$ resonance, we obtain an estimation for the branching ratio of the $H\\to \\gamma \\gamma \\gamma$ decay. Specifically, it is found that $BR(H\\to \\gamma \\gamma \\gamma)\\lesssim BR(H\\to \\gamma Z)BR_{Exp}(Z\\to \\gamma \\gamma)$, whi"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1409.3889","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"}
