Thermal Gauge Theory, Effective Action and Z(N) Symmetry

One of the salient features of high temperature gluodynamics is the Z(N) groundstate degeneracy, key to the understanding of the transition. On the other hand impressive progress has been obtained with effective theories, that seemingly lack Z(N) symmetry. We give a simple unified desciption of the two. As a very useful byproduct we get a natural infrared regulator and show its expediency by calculating the next to leading order in the Debye mass. Higher order corrections to bulk free energy and domainwall surface tension are discussed.

Wilson line in high temperature particle physics

The physics of the Wilson line leads to new developments in high temperature particle physics. The main tool is the effective action for a given fixed value of the phase of the Wilson line. It furnishes a gauge invariant infrared cut off, and yields for small values of the phases a systematic procedure for obtaining a power series in the coupling g and glog(1/g). It breaks the centergroup symmetry of the gauge group only at high temperature so leads to domain walls disappearing at low temperatures. It shows long lived metastable states in the standard model, SU(5), SO(10) and its SUSY partners, with possibilities for CP violation and thermal inflation.

Interfaces in hot gauge theory

The string tension at low T and the free energy of domain walls at high T can be computed from one and the same observable. We show by explicit calculation that domain walls in hot Z(2) gauge theory have good thermodynamical behaviour. This is due to roughening of the wall, which expresses the restoration of translational symmetry.

CP Violating Metastable States and Baryogenesis in the Hot Standard Model

We discuss a novel form of CP violation in the standard model. It takes place at temperatures of the order of the electroweak transition, when two regions with different values of the Wilson line are juxtaposed. This CP violation is maximal. A sufficient condition is simply the existence of a long-lived metastable state; this can occur for fewer than three generations, and also in the minimal susy standard model. It leads to baryogenesis in all of these models.
