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.

On a gauge-invariant deformation of a classical gauge-invariant theory
Journal of High Energy Physics, 2021 We consider a general gauge theory with independent generators and study the problem of gauge-invariant deformation of initial gauge-invariant classical action.

Chiral Schwinger model with Faddeevian anomaly and its BRST quantization
European Physical Journal C: Particles and Fields, 2020 We consider chiral Schwinger model with Faddeevian anomaly, and carry out the quantization of both the gauge-invariant and non-invariant version of this model has been.

A worldline theory for supergravity
Journal of High Energy Physics, 2020 The N $$ \mathcal{N} $$ = 4 supersymmetric spinning particle admits several consistent quantizations, related to the gauging of different subgroups of the SO(4) R-symmetry on the worldline.

An excursion into the string spectrum
Journal of High Energy Physics, 2023 We propose a covariant technique to excavate physical bosonic string states by entire trajectories rather than individually. The approach is based on Howe duality: the string’s spacetime Lorentz algebra commutes with a certain inductive limit of sp ...

Einstein gravity from the N = 4 $$ \mathcal{N}=4 $$ spinning particle
Journal of High Energy Physics, 2018 We obtain a manifestly background independent BRST quantization of the N = 4 $$ \mathcal{N}=4 $$ supersymmetric spinning particle. We show that nilpotency of the BRST charge Q implies the Einstein equations admitting a cosmological constant of indefinite

Finite BRST–antiBRST transformations in Lagrangian formalism
Physics Letters B, 2014 We continue the study of finite BRST–antiBRST transformations for general gauge theories in Lagrangian formalism initiated in [1], with a doublet λa, a=1,2, of anticommuting Grassmann parameters, and find an explicit Jacobian corresponding to this change

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 ...
