Superfield approach to nilpotent symmetries for QED from a single restriction: an alternative to horizontality condition

We derive together the exact local, covariant, continuous and off-shell nilpotent Becchi-Rouet-Stora-Tyutin (BRST) and anti-BRST symmetry transformations for the U(1) gauge field (Aμ), the (anti-)ghost fields ((C̄)C) and the Dirac fields (ψ, ψ̄) of the Lagrangian density of a four (3+1)-dimensional QED by exploiting a single restriction on the six (4, 2)dimensional supermanifold. A set of four ev...

A generalization of the horizontality condition in the superfield approach to nilpotent symmetries for QED with complex scalar fields

We provide a generalization of the horizontality condition of the usual superfield approach to Becchi-Rouet-Stora-Tyutin (BRST) formalism to obtain the (anti-)BRST symmetry transformations for all the fields of a four (3 + 1)-dimensional interacting 1-form U(1) gauge theory (QED) within the framework of the augmented superfield formalism. In the above interacting gauge theory, there is an expli...
