Abstract

We discuss the complete sets of the off-shell nilpotent i.e. \s^2 {ab} = 0\ and absolutely anticommuting i.e. \s b s {ab} + s {ab} s b = 0\ Becchi–Rouet–Stora–Tyutin BRST \s b\ and anti-BRST \s {ab}\ symmetries for the \3+1\-dimensional 4D gauge-invariant massive 2-form theory within the framework of an augmented superfield approach to the BRST formalism. In this formalism, we obtain the coupled but equivalent Lagrangian densities which respect both BRST and anti-BRST symmetries on the constrained hypersurface defined by the Curci–Ferrari type conditions. The absolute anticommutativity property of the anti- BRST transformations and corresponding generators is ensured by the existence of the Curci–Ferrari type conditions which emerge very naturally in this formalism. Furthermore, the gauge-invariant restriction plays a decisive role in deriving the proper anti- BRST transformations for the Stückelberg-like vector field.
