Fermion mass hierarchy in an extended left-right symmetric model
We present a Left-Right symmetric model that explains the mass hierarchy of charged fermions within the Standard Model. The explanation uses both tree-level and radiative seesaw mechanisms. It introduces a three-loop radiative inverse seesaw mechanism to generate the small masses of light neutrinos, with Dirac and Majorana submatrices forming at the one-loop level. The model also includes a global $U(1)_X$ symmetry, which stabilizes Dark Matter candidates after spontaneous breaking. The model is consistent with electroweak precision observables, the electron and muon anomalous magnetic moments as well as with the constraints arising from charged lepton flavor violation, dark matter and the 95 GeV diphoton excess.
