Neutrino masses and dark matter in gauge theories for baryon and lepton numbers — •Michael Duerr1, Pavel Fileviez Perez1, Manfred Lindner1, and Mark B. Wise2 — 1Max-Planck-Institut für Kernphysik, Heidelberg, Germany — 2Caltech, Pasadena, CA, USA
In the Standard Model, baryon and lepton numbers are accidental global symmetries of the renormalizable couplings. We present viable extensions of the Standard Model, in which baryon and lepton numbers are local gauge symmetries that are spontaneously broken at a low scale. Focussing on neutrino masses and dark matter, we discuss phenomenological implications of these theories.
