BRST Extension of Geometric Quantization [PDF]
Foundations of Physics, 2007 Consider a physical system for which a mathematically rigorous geometric quantization procedure exists. Now subject the system to a finite set of irreducible first class (bosonic) constraints. It is shown that there is a mathematically rigorous BRST quantization of the constrained system whose cohomology at ghost number zero recovers the constrained ...

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 ...

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 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.

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.

BRST-anti-BRST covariant theory for the second class constrained systems. A general method and examples [PDF]
, 1998 The BRST-anti-BRST covariant extension is suggested for the split involution quantization scheme for the second class constrained theories. The constraint algebra generating equations involve on equal footing a pair of BRST charges for second class ...

BRST-CO-BRST QUANTIZATION OF REPARAMETRIZATION-INVARIANT THEORIES [PDF]
International Journal of Modern Physics A, 1998 We study some reparametrization-invariant theories in the context of the BRST-co-BRST quantization method. The method imposes restrictions on the possible gauge-fixing conditions and leads to well-defined inner product states through a gauge regularization procedure. Two explicit examples are treated in detail.

Proca theory from the spinning worldline
Journal of High Energy Physics, 2022 We obtain Proca field theory from the quantisation of the N $$ \mathcal{N} $$ = 2 supersymmetric worldline upon supplementing the graded BRST-algebra with an extra multiplet of oscillators.

Irreducible Hamiltonian BRST analysis of Stueckelberg coupled p-form gauge theories [PDF]
, 1999 The irreducible Hamiltonian BRST symmetry for p-form gauge theories with Stueckelberg coupling is derived. The cornerstone of our approach is represented by the construction of an irreducible theory that is equivalent from the point of view of the BRST ...

Physics Letters B, 2020 In present paper a quantization scheme proposed recently by Morris (arXiv:1806.02206 [hep-th]) is analyzed. This method is based on idea to combine the renormalization group with the BV-formalism in a unique quantization procedure.
