Consequently, this establishes the veracity of statements that were long observed or expected to be true, but not proven, e.g., operators with B-L=0 are of even dimension, B-L must be an even number, etc. These results remain true even if the SM is augmented by any number of right-handed neutrinos with L=1.", "revisions": [ { "version": "v1", "updated": "2016-04-19T20:00:13.000Z" } ], "analyses": { "keywords": [ "lepton number", "standard model", "baryon number", "operator dimension", "results remain true" ], "note": { "typesetting": "TeX", "pages": 5, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2016arXiv160405726K" } } }
