Seesaw Model of Neutrino Mass Estimation with a Dirac Mass of 585 GeV Electroweak Fermion and the Unified Stoney Mass

In this work, we propose a novel approach to estimate neutrino masses using a Dirac seesaw mechanism grounded in our 4G model of final unification. The framework utilizes a Dirac mass of 585 GeV, an assumed electroweak fermion having its existence connected with nuclear structure and the unified Stoney mass of 1.859e-9 kg. Neutrino mass hierarchies are constructed using integer scaling parameters 1,2 and 3 connected with the lepton series and square roots of charged lepton mass ratios associated with electron. Estimated rest masses of the three neutrinos are 0.289 meV/c², 8.297 meV/c² and 51.03 meV/c² respectively, yielding a total neutrino mass sum of 59.63 meV/c². Including antineutrinos, the combined mass sum is 0.12 eV/c², consistent with cosmological constraints and the Dirac neutrino hypothesis. For data fitting, we consider a coefficient of 0.88. This coefficient may be refined with future observations and theoretical developments.
