{"arxiv_id":"hep-ph/0408264","title":"Atmospheric neutrinos as probes of neutrino-matter interactions","abstract":"Neutrino oscillation experiments provide a unique tool for probing neutrino-matter interactions, especially those involving the tau neutrino. We describe the sensitivity of the present atmospheric neutrino data to these interactions in the framework of a three-flavor analysis. Compared to the two-flavor nu_mu-nu_tau analyses, we find qualitatively new features, in particular, that large non-standard interactions, comparable in strength to those in the Standard Model, can be consistent with the data. The existence of such interactions could imply a smaller value of the neutrino mixing angle and larger value of the mass-squared splitting than in the case of standard interactions only. This and other effects of non-standard interactions may be tested in the next several years by MINOS, KamLAND and solar neutrino experiments.","primary_cat":"hep-ph","cross_cats":[],"submitted_at":"2004-08-24T21:41:15+00:00","latest_version":2,"source":"arxiv","source_label":"arXiv","source_url":null,"has_pdf":true,"has_source":false,"verdict":"CONDITIONAL","confidence":"HIGH","one_line_summary":"Large non-standard neutrino-matter interactions, up to order Standard Model strength, remain consistent with atmospheric neutrino data once three-flavor mixing is included.","novelty_score":7.0,"correctness_risk":"low","formal_verification":"none","upvotes":0,"downvotes":0,"pith_score":0,"inbound_count":43,"_links":{"html":"https://pith.science/paper/hep-ph/0408264","verdict":"/api/v1/verdicts/hep-ph/0408264"}}
