Massive selfdual perturbed gauge theory
نویسنده
چکیده
Spontaneously broken gauge theories are described as a perturbation of selfdual gauge theory. Instead of the incorporation of scalar degrees of freedom, the massive component of the gauge field is obtained from an anti-selfdual field strength consisting of three components before gauge fixing. The interactions describe a massive gauge theory that is non-polynomial with an expansion containing an infinite number of terms. The Lagrangian generalizes the form of the axial anomaly in two dimensions.

Simplifying Algebra in Feynman Graphs Part III: Massive Vectors
A T-dualized selfdual inspired formulation of massive vector fields coupled to arbitrary matter is generated; subsequently its perturbative series modeling a spontaneously broken gauge theory is analyzed. The new Feynman rules and external line factors are chirally minimized in the sense that only one type of spin index occurs in the rules. Several processes are examined in detail and the cross...
متن کاملToroidal Compactification in String Theory from Chern-Simons Theory
A detailed study of the charge spectrum of three dimensional Abelian Topological Massive Gauge Theory (TMGT) is given. When this theory is defined on a manifold with two disconnected boundaries there are induced chiral Conformal Field Theories (CFT’s) on the boundaries which can be interpreted as the left and right sectors of closed strings. We show that Narain constraints on toroidal compactif...
متن کاملPhase Structure of Compact QED from the Sine-Gordon/Massive Thirring Duality
We discuss a phase structure of compact QED in four dimensions by considering the theory as a perturbed topological model. In this scenario we use the singular configuration with an appropriate regularization, and so obtain the results similar to the lattice gauge theory due to the effect of topological objects. In this paper we calculate the thermal pressure of the topological model by the use...
متن کاملG / G models as the strong coupling limit of topologically massive gauge theory
We show that the problem of computing the vacuum expectation values of gauge invariant operators in the strong coupling limit of topologically massive gauge theory is equivalent to the problem of computing similar operators in the G k /G model where k is the integer coefficient of the Chern-Simons term. The G k /G model is a topological field theory and many correlators can be computed analytic...
متن کاملBulk Kalb-Ramond field in Randall Sundrum scenario
We have considered the most general gauge invariant five-dimensional action of a second rank antisymmetric Kalb-Ramond tensor gauge theory, including a topological term of the form ǫBABHLMN in a Randall-Sundrum scenario. Such a tensor field BAB (whose rank-3 field strength tensor is HLMN ), which appears in the massless sector of a heterotic string theory, is assumed to coexist with the gravity...
