  We derive the off-shell nilpotent (fermionic) (anti-)BRST symmetry
transformations by exploiting the (anti-)chiral superfield approach (ACSA) to
Becchi-Rouet-Stora-Tyutin (BRST) formalism for the interacting Abelian 1-form
gauge theories where there is a coupling between the U(1) Abelian 1-form gauge
field and Dirac as well as complex scalar fields. We exploit the (anti-)BRST
invariant restrictions on the (anti-)chiral superfields to derive the fermionic
symmetries of our present D-dimensional Abelian 1-form gauge theories. The
novel observation of our present investigation is the derivation of the
absolute anticommutativity of the nilpotent (anti-)BRST charges despite the
fact that our ordinary D-dimensional theories are generalized onto the (D,
1)-dimensional (anti-)chiral super submanifolds (of the general (D,
2)-dimensional supermanifold) where only the (anti-)chiral expansions of the
(anti-)chiral superfields have been taken into account. We also discuss the
nilpotency of the (anti-)BRST charges and (anti-)BRST invariance of the
Lagrangian densities of our present theories within the framework of ACSA to
BRST formalism.
