Finite field-dependent symmetry in the Thirring model
Abstract
In this paper, we consider a D-dimensional massive Thirring model with (2<D<4). We derive an extended BRST symmetry of the theory with finite field-dependent parameter. Further we compute the Jacobian of functional measure under such an extended transformation. Remarkably, we find that such a Jacobian extends the BRST exact part of the action which leads to a mapping between different gauges. We illustrate this with the help of the Lorentz and R_ξ gauges. We also discuss the results in the Batalin-Vilkovisky framework.
