Dynamical equations for fermion masses are derived using high scale universal mass generation and consequent mass evolution due to $SU(3), SU(2)$, and U(1$ gauge interaction. Assuming mass generation at the GUT scale $M=10^{14}$ GeV, one…

In the flavour dependence hadrons and leptons show a mass relation, not expected in the Standard Model. This can be understood in an analysis, based on a particle Lagrangian with Maxwell term, boson-boson coupling and massless fermions…
