The Structure of Screening in QED
Emili Bagan, Martin Lavelle, David McMullan +1
The possibility of constructing charged particles in gauge theories has long been the subject of debate. In the context of QED we have shown how to construct operators which have a…
Charges from Dressed Matter: Physics and Renormalisation
Emili Bagan, Martin Lavelle, David McMullan
Gauge theories are characterised by long range interactions. Neglecting these interactions at large times, and identifying the Lagrangian matter fields with the asymptotic physical…
Charges from Dressed Matter: Construction
Emili Bagan, Martin Lavelle, David McMullan
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 w…
The Effective Electroweak Chiral Lagrangian: The Matter Sector
Emili Bagan, Domenec Espriu, Julian Manzano
We parametrize in a model-independent way possible departures from the minimal Standard Model predictions in the matter sector. We only assume the symmetry breaking pattern of the…
Radiative Corrections to the Decay and the Heavy Quark Limit
E. Bagan, P. Ball, V. M. Braun
We calculate radiative corrections to the light-cone sum rule for the semileptonic form factor in decays and thus remove the major uncertainty in determining the CKM mixi…
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…
