Physics beyond Lorenz gauge: General Electrodynamics

The development of the subject is through Generalized Maxwell’s Equations which involves scalar fields in place of Lorentz condition. Also, General Electrodynamics for massive particles both fermions and bosons and quarks are developed. This gauge invariant theory is applied to study Standard Model for unification of electromagnetic strong and weak interaction. The results of General Electrodynamics and of Standard Model are in agreement with the experimental data in Particle Physics.
