Time reflection and the dynamics of particles and antiparticles

TL;DR

This paper explores a fully covariant formulation of electrodynamics under the Poincaré group, examining how particle and antiparticle dynamics emerge through transformations, with implications for Feynman and Dirac interpretations.

Contribution

It introduces a covariant electrodynamics framework that incorporates particle-antiparticle dynamics via Poincaré transformations, advancing the understanding of fundamental symmetries.

Findings

Demonstrates how Poincaré transformations influence particle-antiparticle identification.

Provides a covariant approach to electrodynamics consistent with special relativity.

Links transformation components to particle and antiparticle behavior.

Abstract

In this paper we continue our analysis of a formulation of electrodynamics fully covariant under the full Poincar\'e group. Transformations under the four different components of the group force on us the introduction of particles, either in the identification by Feynman or in the identification of Dirac.
