Its implications on the l_i --> l_j \\gamma \\gamma, and l_i --> l_j e^+ e^- transitions are investigated. Assuming 2 m_e < m_\\phi <m_\\mu, it is found that the inequality B(l_i --> l_j \\gamma \\gamma)<B(l_i --> l_j e^+ e^-) is hold. The experimental constraints on the decays l_i --> l_j \\gamma, l_i --> l_j l_k l_k, and l_i --> l_j \\gamma \\gamma are used to bound the \\phi l_i l_j couplings."},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"hep-ph/0511331","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"}
