The Quantum Fermionic Charged Particle Self-Interaction Problem within the Fock Multitime and Feynman Proper Time Paradigms

Abstract

A quantum fermionic massless charged particle self-interacting with its own self-generated bosonic electromagnetic field is reanalyzed in the framework of the Fock multitime and Feynman proper time paradigms. The self-interaction phenomenon structure is studied within the method based on a suitably renormalized quantum Fock space. The fermionic charged particle mass spectrum is also discussed.
