Query: Nilpotent Symmetries in Jackiw-Pi Model: Augmented Superfield Approach   We derive the complete set of off-shell nilpotent (s^2_{(a)b} = 0) and
absolutely anticommuting (s_b s_{ab} + s_{ab} s_b = 0)
Becchi-Rouet-Stora-Tyutin (BRST) (s_b) as well as anti-BRST symmetry
transformations (s_{ab}) corresponding to the combined Yang-Mills and
non-Yang-Mills symmetries of the (2 + 1)-dimensional Jackiw-Pi model within the
framework of augmented superfield formalism. The absolute anticommutativity of
the (anti-)BRST symmetries is ensured by the existence of two sets of
Curci-Ferrari (CF) type of conditions which emerge naturally in this formalism.
The presence of CF conditions enables us to derive the coupled but equivalent
Lagrangian densities. We also capture the (anti-)BRST invariance of the coupled
Lagrangian densities in the superfield formalism. The derivation of the
(anti-)BRST transformations of the auxiliary field \rho is one of the key
findings which can neither be generated by the nilpotent (anti-)BRST charges
nor by the requirements of the nilpotency and/or absolute anticommutativity of
the (anti-)BRST transformations. Finally, we provide a bird's-eye view on the
role of auxiliary field for various massive models and point out few striking
similarities and some glaring differences among them.
