With the help of the commutators of lepton mass matrices in matter, we show that this kind of contamination is negligible for a variety of experiments provided the neutrino beam energy E and the baseline length L satisfy the condition 10^{-7} (L/km)^2 (GeV/E) << 1. The same observation is true for the CP-violating term of the asymmetry between \\nu_\\alpha \\to \\nu_\\beta and \\bar{\\nu}_\\alpha \\to \\bar{\\nu}_\\beta oscillations in matter.", "revisions": [ { "version": "v3", "updated": "2013-06-27T00:10:21.000Z" } ], "analyses": { "subjects": [ "14.60.Pq", "13.10.+q", "25.30.Pt" ], "keywords": [ "leptonic commutators", "neutrino oscillations", "long-baseline neutrino experiment", "neutrino beam energy", "terrestrial matter effects" ], "tags": [ "journal article" ], "publication": { "doi": "10.1103/PhysRevD.88.017301", "journal": "Physical Review D", "year": 2013, "month": "Jul", "volume": 88, "number": 1, "pages": "017301" }, "note": { "typesetting": "LaTeX", "pages": 7, "language": "en", "license": "arXiv", "status": "editable", "inspire": 1230938, "adsabs": "2013PhRvD..88a7301X" } } }
