We argue that the Witten's loop mechanism for the right-handed Majorana neutrino mass generation identified originally in the SO(10) grand unification context can be successfully adopted to the class of the simplest flipped SU(5) models. In such a framework, the main drawback of the SO(10) prototype, in particular, the generic tension among the gauge unification constraints and the absolute neutrino mass scale is alleviated and a simple yet potentially realistic and testable scenario emerges.

  1. Thermal leptogenesis in minimal unified models

    hep-ph 2025-06 conditional novelty 4.0 of 10

    Thermal leptogenesis in minimal flipped SU(5) and SO(10) models tightly constrains their flavour parameters, yielding a lightest-neutrino mass below 0.03 eV and a B-L breaking scale near 10^12.5 GeV.

  2. Baryogenesis through leptogenesis in the minimal flipped $SU(5)$ with radiative seesaw

    hep-ph 2025-06 conditional novelty 2.0 of 10

    In the minimal flipped SU(5) model with radiative seesaw, successful thermal leptogenesis implies an upper limit on the lightest neutrino mass of about 3 x 10^-2 eV, testable at KATRIN.
