Conserved Quantities in Noncommutative Principal Chiral Model with Wess-Zumino Term
U. Saleem, M. Hassan, M. Siddiq
Abstract
We construct noncommutative extension of U(N) principal chiral model with Wess-Zumino term and obtain an infinite set of local and non-local conserved quantities for the model using iterative procedure of Brezin et.al BIZZ. We also present the equivalent description as Lax formalism of the model. We expand the fields perturbatively and derive zeroth- and first-order equations of motion, zero-curvature condition, iteration method, Lax formalism, local and non-local conserved quantities.
