If the theory is supersymmetric and the origin of the masses is a see-saw mechanism, we show that the prediction for BR(mu --> e, gamma) is in general larger than the experimental upper bound, especially if the largest Yukawa coupling is O(1) and the solar data are explained by a large angle MSW effect, which recent analyses suggest as the preferred scenario. Our analysis is bottom-up and completely general, i.e. it is based just on observable low-energy data. The work generalizes previous results of the literature, identifying the dominant contributions. Application of the results to scenarios with approximate top-neutrino unification, like SO(10) models, rules out most of them unless the leptonic Yukawa matrices satisfy very precise requirements. Other possible ways-out, like gauge mediated SUSY breaking, are also discussed.","external_url":"https://arxiv.org/abs/hep-ph/0103065","cited_by_count":null,"metadata_source":"pith","metadata_fetched_at":"2026-05-23T00:22:18.821602+00:00","pith_arxiv_id":"hep-ph/0103065","created_at":"2026-05-10T22:05:49.810559+00:00","updated_at":"2026-05-23T00:22:18.821602+00:00","title_quality_ok":false,"display_title":"Oscillating neutrinos andµ→e, γ","render_title":"Oscillating neutrinos andµ→e, γ"},"hub":{"state":{"work_id":"71f351c1-bb52-4500-8a4f-29d0afa01bf6","tier":"hub","tier_reason":"10+ Pith inbound or 1,000+ external citations","pith_inbound_count":22,"external_cited_by_count":null,"distinct_field_count":2,"first_pith_cited_at":"2025-03-13T13:46:26+00:00","last_pith_cited_at":"2026-05-21T15:58:15+00:00","author_build_status":"not_needed","summary_status":"needed","contexts_status":"needed","graph_status":"needed","ask_index_status":"not_needed","reader_status":"not_needed","recognition_status":"not_needed","updated_at":"2026-05-29T20:00:19.660503+00:00","tier_text":"hub"},"tier":"hub","role_counts":[{"context_role":"background","n":8},{"context_role":"method","n":4}],"polarity_counts":[{"context_polarity":"background","n":8},{"context_polarity":"use_method","n":4}],"runs":{},"summary":{},"graph":{},"authors":[]}}
