Supersymmetry with Lorentz Symmetry Violation
I. T. Drummond
We study two (massless free field) models, a photon/photino model with a vector gauge field and a Majorana spinor field, and a Wess-Zumino model. They each exhibit Lorentz symmetry…
Lorentz Symmetry Violation in QCD and the Frustration of Asymptotic Freedom
I. T. Drummond
We study the effect of Lorentz symmetry violation (LSV) on the behaviour at high energy of SU(N) gauge theory with quarks in the fundamental representation. The approach is similar…
Bimetric QED
I. T. Drummond
We study, as a model of Lorentz symmetry breaking, the quantisation and renormalisation of an extension of QED in a flat spacetime where the photons and electrons propagate differe…
Quantum Field Theory in a Multi-Metric Background
I. T. Drummond
By means of simple models in a flat spacetime manifold we examine some of the issues that arise when quantizing interacting quantum fields in multi-metric backgrounds. In particula…
QCD Pressure and the Trace Anomaly
I T Drummond, R R Horgan, P V Landshoff +1
Exact relations between the QCD thermal pressure and the trace anomaly are derived. These are used, first, to prove the equivalence of the thermodynamic and the hydrodynamic pressu…
Eliminating Infrared Divergences in the Pressure
I. T. Drummond, R. R. Horgan, P. V. Landshoff +1
The pressure of a system in thermal equilibrium is expressed as a mass integral over a sum of thermal propagators. This allows a Dyson resummation and is used to demonstrate that p…
