Gauged WZW Models
As shown by Witten the N = 1 supersymmetric gauged WZW model based on a group G has an extended N = 2 supersymmetry if the gauged subgroup H is so chosen that G/H is Kähler. We extend Witten’s result and prove that the N = 1 supersymmetric gauged WZW models over G×U(1) are actually invariant under N = 4 superconformal transformations if the gauged subgroup H is such that G/(H × SU(2)) is a quat...
متن کامل- 55 Extra Observables in Gauged WZW Models
It is known that Liouville theory can be represented as an SL(2,R) gauged WZW model. We study a two dimensional field theory which can be obtained by analytically continuing some of the variables in the SL(2,R) gauged WZW model. We can derive Liouville theory from the analytically continued model, ( which is a gauged SL(2, C)/SU(2) model, ) in a similar but more rigorous way than from the origi...
متن کاملDeformed Coset Models From Gauged WZW Actions
A general Lagrangian formulation of integrably deformed G/H-coset models is given. We consider the G/H-coset model in terms of the gauged Wess-Zumino-Witten action and obtain an integrable deformation by adding a potential energy term Tr(gTgT̄ ), where algebra elements T, T̄ belong to the center of the algebra h associated with the subgroup H. We show that the classical equation of motion of the ...
متن کاملGauged WZW models and non-Abelian duality.
We consider WZW models based on the non-semi-simple algebras that they were recently constructed as contractions of corresponding algebras for semi-simple groups. We give the explicit expression for the action of these models, as well as for a generalization of them, and discuss their general properties. Furthermore we consider gauged WZW models based on these non-semi-simple algebras and we sh...
