CHIRAL SYMMETRIES OF THE WZNW MODEL BY HAMILTONIAN METHODS
B. Sazdović
Abstract
The connection between the Kac-Moody algebras of currents and the chiral symmetries of the two dimensional WZNW model is clarified. It is shown that only the zero modes of the Kac-Moody currents are the first class constraints, and that, consequently, the corresponding gauge symmetries are chiral.
