Principles of BRST quantization
Nuclear Physics B, 1989 Abstract The BRST quantization as a quantization method ised. It is pointed out that all formal manipulations are only valid if all inner products in the original state space are finite. This restriction is also shown to be necessary in order to obtain the correct results for trivial models.

Modified 2D Proca Theory: Revisited under BRST and (Anti‐)chiral Superfield Formalisms
Advances in High Energy Physics, Volume 2020, Issue 1, 2020., 2020 Within the framework of Becchi‐Rouet‐Stora‐Tyutin (BRST) approach, we discuss mainly the fermionic (i.e., off‐shell nilpotent) (anti‐)BRST, (anti‐)co‐BRST, and some discrete dual symmetries of the appropriate Lagrangian densities for a two (1 + 1)‐dimensional (2D) modified Proca (i.e., a massive Abelian 1‐form) theory without any interaction with ...

Stability and Hamiltonian BRST-invariant deformations in Podolsky's generalized electrodynamics
Nuclear Physics B, 2021 We study the problem of stability in Podolsky's generalized electrodynamics by constructing a series of 2-parametric bounded conserved quantities. In this way, we show that the 00-component of the energy-momentum tensors could be positive definite and ...

Braided quantum electrodynamics
Journal of High Energy Physics, 2023 The homotopy algebraic formalism of braided noncommutative field theory is used to define the explicit example of braided electrodynamics, that is, U(1) gauge theory minimally coupled to a Dirac fermion.

BRST quantization and equivariant cohomology: localization with asymptotic boundaries
Journal of High Energy Physics, 2018 We develop BRST quantization of gauge theories with a soft gauge algebra on spaces with asymptotic boundaries. The asymptotic boundary conditions are imposed on background fields, while quantum fluctuations about these fields are described in terms of ...

Feynman diagrams in four-dimensional holomorphic theories and the Operatope
Journal of High Energy Physics, 2023 We study a class of universal Feynman integrals which appear in four-dimensional holomorphic theories. We recast the integrals as the Fourier transform of a certain polytope in the space of loop momenta (a.k.a. the “Operatope”).

Quantization of a generally covariant gauge system with two super Hamiltonian constraints [PDF]
, 2001 The Becci-Rouet-Stora-Tyutin (BRST) operator quantization of a finite-dimensional gauge system featuring two quadratic super Hamiltonian and m linear supermomentum constraints is studied as a model for quantizing generally covariant gauge theories.
