Gauge singlet neutrinos are assumed to propagate in one extra dimension, giving rise to an infinite tower of states in the effective four-dimensional theory. It is shown that this leads to small lepton-number violating entries in the neutrino mass matrix, which can violate unitarity on the order of one per cent.", "revisions": [ { "version": "v1", "updated": "2009-07-01T09:39:28.000Z" } ], "analyses": { "subjects": [ "12.10.-g", "14.60.Pq" ], "keywords": [ "extra dimension", "unitarity violation", "extra compact spacelike dimensions", "gauge singlet neutrinos", "sequential neutrino mixing matrix" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Physical Review D", "year": 2009, "month": "Oct", "volume": 80, "number": 7, "pages": "075013" }, "note": { "typesetting": "TeX", "pages": 16, "language": "en", "license": "arXiv", "status": "editable", "inspire": 824655, "adsabs": "2009PhRvD..80g5013B" } } }
