Three-loop neutrino masses via new massive gauge bosons from E-6 GUT uri icon


  • 2018 authors. Published by the American Physical Society. We propose a SU(3)CSU(2)LSU(2)NU(1)Y model arising from E6 grand unified theory. We show that the tiny neutrino masses in this model can be generated at the three-loop involving the SU(2)N gauge bosons. With Yukawa couplings around 0.01 or larger and TeV-scale SU(2)N gauge bosons, we show that the neutrino oscillation data can be explained naturally by presenting a concrete benchmark set of input parameters. All new particles are around the TeV scale. Thus our model can be tested at the ongoing/future collider experiments.
