abstract

The standard model of quarks and leptons is extended to include the gauge symmetry $U(1)_\chi$ which comes from $SO(10) \to SU(5) \times U(1)_\chi$. The radiative generation of Dirac neutrino masses through dark matter is discussed in two examples. One allows for light Dirac fermion dark matter. The other allows for self-interacting scalar dark matter with a light scalar mediator which decays only to two neutrinos.

  1. Lepton flavor violation in the Majorana and Dirac scotogenic models

    hep-ph 2025-02 conditional novelty 5.0 of 10

    In the Majorana and Dirac scotogenic models, the 3-body tau decay τ→3μ can reach branching ratios of about 10^-10 and 10^-11 respectively, after muon constraints and perturbativity are imposed.

  2. Dirac neutrinos in a $SU(2)$ left-right symmetric model

    hep-ph 2019-08 conditional novelty 4.0 of 10

    An SU(2)_L x SU(2)_R x U(1)_{B-L} model with two or three scalar bidoublets and two doublets keeps neutrinos Dirac and aims to remove the small-mass fine-tuning with a third bidoublet.
