Wess-Zumino term for chiral bosons
C. Wotzasek · Physical Review Letters · 1991
We derive the Wess-Zumino term for the chiral-boson model formulated by Sonnenschein using an iterative process, previously introduced by the author in the context of the chiral Schwinger model, that transforms the second-class chiral constraints into first-class ones. Because of the peculiar features of this model the Wess-Zumino term found is made of an infinite number of terms, using an infinite number of auxiliary fields.
