BRST extension of the Faddeev model
arXiv:hep-th/0508120 · doi:10.1103/PhysRevD.72.127701
Abstract
The Faddeev model is a second class constrained system. Here we construct its nilpotent BRST operator and derive the ensuing manifestly BRST invariant Lagrangian. Our construction employs the structure of Stuckelberg fields in a nontrivial fashion.
