A class of two-dimensional Yang–Mills vacua and their relation to the non-linear sigma model
نویسندگان
چکیده
Classical vacuum pure gauge solutions of Euclidean two-dimensional SU(2) Yang–Mills theories are studied. Topologically non-trivial vacua are found in a class of gauge group elements isomorphic to S2. These solutions are unexpectedly related to the solution of the non-linear O(3) model and to the motion of a particle in a periodic potential. PACS: 11.10.Kk, 11.10.Lm.

Fivebranes from gauge theory
We study theories with sixteen supercharges and a discrete energy spectrum. One class of theories has symmetry group SU(2|4). They arise as truncations of N = 4 super Yang Mills. They include the plane wave matrix model, 2+1 super Yang Mills on R × S2 and N = 4 super Yang Mills on R × S/Zk. We explain how to obtain their gravity duals in a unified way. We explore the regions of the geometry tha...
متن کاملYang-Mills Theory as a Deformation of Topological Field Theory, Dimensional Reduction and Quark Confinement
We prove quark confinement in four-dimensional QCD based on the criterion of area law of Wilson loop. First, Yang-Mills theory with a non-Abelian gauge group G is reformulated as a deformation of a novel topological field theory. Next, a special class of topological field theories is defined by both BRST and anti-BRST exact action corresponding to the maximal abelian gauge leaving the maximal t...
متن کاملOn the Analog Strong Cp Problem in the Cp N −1 Models A
Non-perturbative effects can introduce CP violation into the strong interactions. Since no such violations of this discrete symmetry have been observed, an avoidance mechanism must be operative. Although many proposals have been suggested to resolve this issue, the strong CP problem remains one of the outstanding low-energy mysteries of the standard model of particle physics. A four-dimensional...
متن کاملDifferential Transform Method to two-dimensional non-linear wave equation
In this paper, an analytic solution is presented using differential transform method (DTM) for a class of wave equation. The emphasis is on the nonlinear two-dimensional wave equation. The procedures introduced in this paper are in recursive forms which can be used to obtain the closed form of the solutions, if they are required. The method is tested on various examples, and the results reveal ...
متن کاملHigher-dimensional WZW Model on Kähler Manifold and Toroidal Lie Algebra
We construct a generalization of the two-dimensional Wess-Zumino-Witten model on a 2n-dimensional Kähler manifold as a group-valued non-linear sigma model with an anomaly term containing the Kähler form. The model is shown to have an infinitedimensional symmetry which generates an n-toroidal Lie algebra. The classical equation of motion turns out to be the Donaldson-Uhlenbeck-Yau equation, whic...
