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 ...

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.

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.

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 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.

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

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

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

Fedosov Deformation Quantization as a BRST Theory [PDF]
Communications in Mathematical Physics, 2001 The relationship is established between the Fedosov deformation quantization of a general symplectic manifold and the BFV-BRST quantization of constrained dynamical systems. The original symplectic manifold $\mathcal M$ is presented as a second class constrained surface in the fibre bundle ${{\mathcal T}^*_ρ}{\mathcal M}$ which is a certain ...
