摘要：

Hamiltonian reduction of WZW theories involving constraints with half integer conformal weight is analyzed. The reduced system can be described in terms of an effective action that corresponds to a generalized Toda system. To obtain this action, the constraints must be imposed on an enlarged phase space that includes weight 1/2 bosons in addition to the WZW degrees of freedom. An example is worked out for which the chiral algebra consists of a bosonic version of the u(N) extended superconformal algebra. A Gauss decomposition of the WZW field leads to a hybrid free field realization of these algebras.
