Construction and Consequences of Coloured Charges in QCD
E. Bagan, M. Lavelle, D. McMullan +2
This talk reports on work aimed at improving our understanding of charged states in gauge theories.Emphasis is placed on different ways of implementingthe gauge invariance of physi…

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…

On Quark Confinement
Martin Lavelle, David McMullan
A sufficient condition for the confinement of quarks is presented. Quarks are shown to be unobservable. Colour singlets are however, observables. The results of deep inelastic scat…
