We discuss an inherent Pauli–Villars regularization in Bopp–Podolsky's generalized
electrodynamics. Introducing gauge-fixing terms for Bopp–Podolsky's generalized …

We present the electromagnetic gauge field interpolation between the instant form and the
front form of the relativistic Hamiltonian dynamics and extend our interpolation of the …

We develop a complete formulation of quantum gauge invariance in light-front dynamics for
interacting theories with massless vector gauge fields in the framework of null-plane causal …

We consider the interaction between a charged scalar boson and the Bopp–Podolsky gauge
fields. The Bopp–Podolsky (BP) electrodynamics possesses both massive and massless …

The instant form and the front form of relativistic dynamics proposed by Dirac in 1949 can be
linked by an interpolation angle parameter δ spanning between the instant form dynamics …

We study quantum electrodynamics (QED) in the light-front dynamical form by using null-
plane causal perturbation theory. We establish the equivalence with instant dynamics for the …

In this paper we used the Fredholm method in Schrödinger's integral equation in the
investigation of the scattering effect near the center of it between a stationary quantum wave …

Na teoria quântica de campos usual, descrita no espaço-tempo de Minkowski, os conceitos
de partícula e antipartícula surgem associados aos estados de energia positiva e negativa …

Gauge fields in the light front are traditionally addressed via the employment of an algebraic
condition n· A= 0 in the Lagrangian density, where Aμ is the gauge field (Abelian or non …

We revisit the proof of equivalence of one loop expressions for fermion self-energy and
vertex correction in light-front QED and covariant QED at the Feynman diagram level and …
