Effective Quarks and Their Interactions
Emili Bagan, Robin Horan, Martin Lavelle +1
This talk will summarise the progress we have made in our programme to both characterise and construct charges in gauge theories. As an application of these ideas we will see how t…

Charged Matter: Physics and Renormalisation
Emili Bagan, Martin Lavelle, David McMullan
Descriptions of the ground state in unbroken gauge theories with charged particles are discussed. In particular it is shown that the on-shell Green's functions and S-matrix element…

Asymptotic Dynamics in Quantum Field Theory - When does the coupling switch off?
Robin Horan, Martin Lavelle, David McMullan
We discuss the approach to asymptotic dynamics due to Kulish and Faddeev. We show that there are problems in applying this method to theories with four point interactions. The sour…
