We demonstrate that the two (1+ 1)-dimensional (2D) free 1-form Abelian gauge theory
provides an interesting field theoretical model for the Hodge theory. The physical …

We demonstrate that the generators for the local, continuous and infinitesimal classical
gauge symmetry transformations in the cases of (1) the Stückelberg-modified massive …

We propose a general framework to study BRST-related transformations. We investigate
different forms of BRST and BRST-related symmetries, realized within a prototypical first …

We demonstrate that the four-dimensional (4D)((3+ 1)-dimensional) free Abelian 2-form
gauge theory presents a tractable field-theoretical model for the Hodge theory where the …

We apply the superfield approach to the toy model of a rigid rotor and show the existence of
the nilpotent and absolutely anticommuting Becchi–Rouet–Stora–Tyutin (BRST) and anti …

Taking the simple examples of an Abelian 1-form gauge theory in two (1+ 1)-dimensions, a 2-
form gauge theory in four (3+ 1)-dimensions and a 3-form gauge theory in six (5+ 1) …

It is shown that two (1+ 1)-dimensional (2D) free Abelian and self-interacting non-Abelian
gauge theories (without any interaction with matter fields) belong to a new class of …

We show the existence of a co (dual)-BRST symmetry for the usual BRST invariant
Lagrangian density of an Abelian gauge theory in two dimensions of space–time where a U …

We show that the Becchi-Rouet-Stora-Tyutin (BRST)/anti-BRST invariant (3+ 1)-dimensional
two-form gauge theory has further nilpotent symmetries (dual BRST/anti-dual BRST) that …

The derivation of the nilpotent Becchi–Rouet–Stora–Tyutin (BRST)-and anti-BRST
symmetries for the matter fields, present in any arbitrary interacting gauge theory, has been …
