Carries out the light-front (null-plane) Hamiltonian analysis of a reduced-order Bopp-Podolsky generalized electrodynamics, in which an auxiliary vector field replaces the higher derivatives of the original model. Using the Dirac-Bergmann algorithm, it derives the full constraint structure, separates first- and second-class constraints, and computes the Dirac brackets, revealing that the auxiliary field carries the Podolsky mass while the gauge field stays massless in a consistent gauge-invariant Abelian theory. Learners see how constrained Hamiltonian dynamics is adapted to light-front coordinates for a massive gauge theory.
Bopp-Podolsky electrodynamics is a higher-derivative generalization of Maxwell's theory that gives the photon a mass while preserving gauge invariance. This paper studies a reduced-order reformulatio…
