Fuzzy Bags and Wilson Lines
I start with an elementary observation about the pressure in the deconfined phase of a SU(3) gauge theory without quarks. This suggests a “fuzzy” bag model for the analogous pressure in QCD, with dynamical quarks. I then sketch how the deconfined phase might be described using an effective theory of Wilson lines. To leading order in weak coupling, the effective electric field appears in a form ...

We generalize the rules for the free fermionic string construction to include other asymmetric orbifolds. Examples are given to illustrate the use of these rules. Typeset using REVTEX
متن کاملWilson Lines and Symmetry Breaking on Orbifolds
A five-dimensional SU(5) grand unified theory is constructed on the orbifold S/Z2, with gauge symmetry breaking accomplished by a background gauge field. The theory is shown to be equivalent to one with gauge symmetry breaking by orbifold boundary conditions — the two pictures are related by a non-periodic gauge transformation. This effective field theory possesses localized explicit breaking o...
متن کاملHeterotic Yukawa couplings and continuous Wilson lines
Realistic heterotic string models require the presence of the Wilson lines. We study the effect of continuous Wilson lines on the heterotic Yukawa couplings and find that the presence of continuous Wilson lines affects the magnitude of the twisted Yukawa couplings resulting in their stronger hierarchy.
متن کاملEffective Theory of Wilson Lines and Deconfinement
To study the deconfining phase transition at nonzero temperature, I outline the perturbative construction of an effective theory for straight, thermal Wilson lines. Certain large, time dependent gauge transformations play a central role. They imply the existence of interfaces, which can be used to determine the form of the effective theory as a gauged, nonlinear sigma model of adjoint matrices....
