We find a significant number of new possibilities where one can generate neutrino masses at the one-loop level by adding only two new types of representations. These models have renormalizable interactions that automatically conserve baryon number. Adding to the minimal standard model a scalar color octet with SU(3) X SU(2) X U(1) quantum numbers, (8,2,1/2), and a fermionic color octet in the fundamental or adjoint representation of SU(2) one can generate neutrino masses in agreement with the experiment. Signals at the LHC, and constraints from flavour violation are briefly discussed.", "revisions": [ { "version": "v2", "updated": "2009-06-24T21:21:18.000Z" } ], "analyses": { "subjects": [ "14.60.Pq", "12.15.Ff", "12.60.Fr", "13.15.+g" ], "keywords": [ "generate neutrino masses", "minimal standard model", "automatically conserve baryon number", "scalar color octet", "fermionic color octet" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Physical Review D", "year": 2009, "month": "Sep", "volume": 80, "number": 5, "pages": "053006" }, "note": { "typesetting": "TeX", "pages": 9, "language": "en", "license": "arXiv", "status": "editable", "inspire": 823297, "adsabs": "2009PhRvD..80e3006P" } } }
