{"arxiv_id":"hep-ph/0501039","title":"See-Saw Energy Scale and the LSND Anomaly","abstract":"The most general, renormalizable Lagrangian that includes massive neutrinos contains ``right-handed neutrino'' Majorana masses of order M. While there are prejudices in favor of M much larger than the weak scale, virtually nothing is known about the magnitude of M. I argue that the LSND anomaly provides, currently, the only experimental hint: M around 1 eV. If this is the case, the LSND mixing angles are functions of the active neutrino masses and mixing and, remarkably, adequate fits to all data can be naturally obtained. I also discuss consequences of this ``eV-seesaw'' for supernova neutrino oscillations, tritium beta-decay, neutrinoless double-beta decay, and cosmology.","primary_cat":"hep-ph","cross_cats":[],"submitted_at":"2005-01-07T00:02:50+00:00","latest_version":1,"source":"arxiv","source_label":"arXiv","source_url":null,"has_pdf":true,"has_source":false,"verdict":"CONDITIONAL","confidence":"MODERATE","one_line_summary":"Placing the right-handed neutrino Majorana mass near 1 eV makes the seesaw mechanism generate active-sterile mixing angles of order 10^-2, matching what the LSND anomaly needs.","novelty_score":5.0,"correctness_risk":"medium","formal_verification":"none","upvotes":0,"downvotes":0,"pith_score":0,"inbound_count":39,"_links":{"html":"https://pith.science/paper/hep-ph/0501039","verdict":"/api/v1/verdicts/hep-ph/0501039"}}
