On the Quantization of Reducible Gauge Systems [PDF]
, 1992 Reducible gauge theories with constraints linear in the momenta are quantized. The equivalence of the reduced phase space quantization, Dirac quantization and BRST quantization is established.

Re-parameterization invariance of FRW model: Supervariable and BRST approaches
Nuclear Physics BWe perform the Becchi-Rouet-Stora-Tyutin (BRST) quantization of a (0+1)-dimensional cosmological Friedmann-Robertson-Walker (FRW) model. This quantization leverages the classical infinitesimal and continuous re-parameterization symmetry transformations ...

Lie algebroids and the geometry of off-shell BRST
Nuclear Physics B, 2021 It is well-known that principal bundles and associated bundles underlie the geometric structure of classical gauge field theories. In this paper, we explore the reformulation of gauge theories in terms of Lie algebroids and their associated bundles. This

GENERALIZED BRST QUANTIZATION AND MASSIVE VECTOR FIELDS [PDF]
International Journal of Modern Physics A, 1998 A previously proposed generalized BRST quantization on inner product spaces for second class constraints is further developed through applications. This BRST method involves a conserved generalized BRST charge Q which is not nilpotent, Q2≠0, but which satisfies Q=δ+δ†, δ2=0, and by means of which physical states are obtained from the projection δ| ph &

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.

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”).

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.

A pure spinor twistor description of the D = 10 superparticle
Journal of High Energy Physics, 2020 We present a novel twistor formulation of the ten-dimensional massless super-particle. This formulation is based on the introduction of pure spinor variables through a field redefinition of another model for the superparticle, and in the new description ...

Relating the Green-Schwarz and Pure Spinor Formalisms for the Superstring
, 2004 Although it is not known how to covariantly quantize the Green-Schwarz (GS) superstring, there exists a semi-light-cone gauge choice in which the GS superstring can be quantized in a conformally invariant manner.
