We study the Higgs sector of a SO(10) grand unified theory which predicts exact conservation of R-parity at all scales and incorporates the see-saw mechanism. We find possible intermediate scales and light states compatible with the constraints coming from the running of the gauge couplings. Such a pattern could lower the SO(10) breaking scale, allowing the d=6 proton decay operators to be comparable in magnitude to the d=5 ones.

  1. Neutrino Masses and Phenomenology in Nnaturalness

    hep-ph 2025-02 unverdicted novelty 5.0

    Nnaturalness generates neutrino mass matrices through multi-sector mixing, excludes democratic couplings, and yields a tower of neutrino eigenstates with theory-determined mass splittings.
