Vacuum Structure of Two-Dimensional Gauge Theories for Arbitrary Lie Groups
Using the well established machinery of Wilson loop calculations we investigate the multiple vacua of two dimensional Yang-Mills theories with infinitely massive adjoint matter. In particular, via group theoretical techniques we calculate string tensions between charges and find the number of vacua for each compact Lie symmetry group. The counting of vacua is in agreement with the standard clas...
متن کاملDimensional Reduction and Vacuum Structure of Quiver Gauge Theory
We describe the structure of the vacuum states of quiver gauge theories obtained via dimensional reduction over homogeneous spaces, in the explicit example of SU(3)-equivariant dimensional reduction of Yang-Mills-Dirac theory on manifolds of the form M × CP . We pay particular attention to the role of topology of background gauge fields on the internal coset spaces, in this case U(1) magnetic m...
متن کاملDeconstructed Higher Dimensional Gauge Theories
The idea of deconstructing higher dimensional gauge theories is reviewed. Its several potential physical applications are also discussed. Higher dimensional gauge theories o er interesting new tools to understand the roots of the Standard Model. Among other things, gauge symmetries can be broken by compacti cation process on singular manifolds, e.g. on orbifolds. Moreover compacti cation on orb...
متن کاملTwo Dimensional Gauge Theories Revisited
Two dimensional quantum Yang-Mills theory is reexamined using a non-abelian version of the Duistermaat-Heckman integration formula to carry out the functional integral. This makes it possible to explain properties of the theory that are inaccessible to standard methods and to obtain general expressions for intersection pairings on moduli spaces of flat connections on a two dimensional surface. ...
متن کاملFixed Points and Vacuum Energy of Dynamically Broken Gauge Theories
We show that if a gauge theory with dynamical symmetry breaking has non-trivial fixed points, they will correspond to extrema of the vacuum energy. This relationship provides a different method to determine fixed points. e-mail : [email protected] e-mail : [email protected]
