BRST extension of the Faddeev model
Hong, Soon-Tae · Niemi, Antti J.
Original · EN
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.
