Superfield lagrangian quantization with extended BRST symmetry [PDF]
Physics Letters B, 2001 We consider possible superfield representations of extended BRST symmetry for general gauge theories within the principle of gauge-fixing based on a generating equation for the gauge functional. We examine admissible superfield choices for an extended antibracket and delta-operator with given algebraic properties and show that only one of these choices

BFV quantization and FFBRST of Christ-Lee model
Nuclear Physics BWe accomplish the Batalin-Fradkin-Vilkovisky (BFV) quantization of the Christ-Lee model in both polar and Cartesian coordinates. We construct the BRST charge along with gauge-fixing function and obtain the BRST invariant effective action. We also procure

On Correspondence of BRST-BFV, Dirac and Refined Algebraic Quantizations of Constrained Systems [PDF]
, 2001 Correspondence between BRST-BFV, Dirac and refined algebraic (group averaging, projection operator) approaches to quantize constrained systems is analyzed. For the closed-algebra case, it is shown that the component of the BFV wave function with maximal (

Proper BRST quantization of relativistic particles [PDF]
, 1993 Recently derived general formal solutions of a BRST quantization on inner product spaces of irreducible Lie group gauge theories are applied to trivial models and relativistic particle models for particles with spin 0, 12 and 1.

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.

Time evolution in general gauge theories defined on inner product spaces
, 1996 As previously shown BRST singlets |s> in a BRST quantization of general gauge theories on inner product spaces may be represented in the form |s>=e^{[Q, \psi]} |\phi> where |\phi> is either a trivially BRST invariant state which only depends on the ...

Fortschritte der Physik, Volume 74, Issue 1, January 2026.Abstract In this article I consider type II superstring in the pure spinor formulation with constant background fields in the context of T‐dualization. First, I prove that bosonic and fermionic T‐dualization commute using already known T‐dual transformation laws for bosonic and fermionic T‐dualization.

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”).

On gauge fixing in the Lagrangian formalism of superfield BRST quantization
, 1999 We propose a modification of the gauge-fixing procedure in the Lagrangian method of superfield BRST quantization for general gauge theories which simultaneously provides a natural generalization of the well-known BV quantization scheme as far as gauge ...

A note on BRST quantization of SU(2) Yang-Mills mechanics [PDF]
, 2005 The quantization of SU(2) Yang-Mills theory reduced to 0+1 space-time dimensions is performed in the BRST framework. We show that in the unitary gauge $A_0 = 0$ the BRST procedure has difficulties which can be solved by introduction of additional singlet
