Current Algebra of Super WZNW Models
نویسنده
چکیده
We derive the current algebra of supersymmetric principal chiral models with a Wess-Zumino term. At the critical point one obtains two commuting super Kac-Moody algebra as expected, but in general there are intertwining fields connecting both right and left sectors, analogously to the bosonic case. Moreover, in the present supersymmetric extension we have a quadratic algebra, rather than an affine Lie algebra, due to the mixing between bosonic and fermionic fields since the purely fermionic sector displays a Lie algebra as well.

Supersymmetric Construction of W-Algebras from Super Toda and WZNW Theories
A systematic construction of super W-algebras in terms of the WZNW model based on a super Lie algebra is presented. These are shown to be the symmetry structure of the super Toda models, which can be obtained from the WZNW theory by Hamiltonian reduction. A classification, according to the conformal spin defined by an improved energymomentum tensor, is discussed in general terms for all super L...
متن کاملAlgebra of Non-local Charges in the O(n) Wznw Model at and beyond Criticality
We derive the classical algebra of the non-local conserved charges in the O(N) WZNW model and analyze its dependence on the coupling constant of the Wess-Zumino term. As in the non-linear sigma model, we find cubic deformations of the O(N) affine algebra. The surprising result is that the cubic algebra of the WZNW non-local charges does not obey the Jacobi identity, thus opposing our expectatio...
متن کاملClassical Wakimoto Realizations of Chiral WZNW Bloch Waves
It is well-known that the chiral WZNW Bloch waves satisfy a quadratic classical exchange algebra which implies the affine Kac-Moody algebra for the corresponding currents. We here obtain a direct derivation of the exchange algebra by inverting the symplectic form on the space of Bloch waves, and give a completely algorithmic construction of its generalized free field realizations that extend th...
متن کاملHamiltonian Reduction and Supersymmetric Toda Models
New formulations of the solutions of N=1 and N=2 super Toda field theory are introduced, using Hamiltonian reduction of the N=1 and N=2 super WZNW Models to the super Toda Models. These pa-rameterisations are then used to present the Hamiltonian formulations of the super Toda theories on the spaces of solutions.
متن کاملOn the Lagrangian Realization of the WZNW Reductions
We develop a phase space path-integral approach for deriving the Lagrangian realization of the models defined by Hamiltonian reduction of the WZNW theory. We illustrate the uses of the approach by applying it to the models of non-Abelian chiral bosons, W -algebras and the GKO coset construction, and show that the well-known Sonnenschein’s action, the generalized Toda action and the gauged WZNW ...
