Charges from dressed matter: Construction

摘要

There is a widespread belief in particle physics that there is no relativistic description of a charged particle. This is claimed to be due to persistent, long range interactions which distort the incoming and outgoing plane waves and generate infrared divergences. In this paper we will show that this is not the case in QED. We construct locally gauge invariant charged fields which do create in and out Fock slates. In a companion paper we demonstrate that the Green's functions of these fields have a good pole structure describing particle propagation. (C) 2000 Academic Press. [References: 62]
