On Real and Virtual Photons in the Davies Theory of Time-Symmetric Quantum Electrodynamics
arXiv:1312.4007
Abstract
This paper explores the distinction between virtual and real photons in the context of the Davies quantum relativistic extension of the Wheeler-Feynman classical electromagnetic theory. An alternative way of understanding this distinction is proposed, based on the transactional model.
