How do constituent quarks arise in QCD? Perturbation theory and the infra-red
E. Bagan, M. Lavelle, D. McMullan +2
We motivate the use of dressed charges by arguing that such objects are needed to describe, e.g., constituent quarks and, in general, physical charged states in gauge theories. We…

Constituent Quarks from QCD: Perturbation Theory and the Infra-red
E. Bagan, M. Lavelle, D. McMullan +2
Systematic approaches to building up gauge invariant descriptions of charged fields, such as electrons or quarks, are described. Physically relevant descriptions must then be singl…

An Infra-Red Finite Electron Propagator
Emili Bagan, Martin Lavelle, David McMullan
We investigate the properties of a dressed electron which reduces, in a particular class of gauges, to the usual fermion. A one loop calculation of the propagator is presented. We…
