Algebra of non-local charges in the O(N) WZNW model at and beyond criticality
L. E. Saltini, A. Zadra
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…

Current Algebra of Super WZNW Models
E. Abdalla, M. C. B. Abdalla, O. H. G. Branco +1
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…
