Supervariable and BRST Approaches to a Reparameterization Invariant Nonrelativistic System
Advances in High Energy Physics, Volume 2021, Issue 1, 2021., 2021 We exploit the theoretical strength of the supervariable and Becchi‐Rouet‐Stora‐Tyutin (BRST) formalisms to derive the proper (i.e., off‐shell nilpotent and absolutely anticommuting) (anti‐)BRST symmetry transformations for the reparameterization invariant model of a nonrelativistic (NR) free particle whose space (x) and time (t) variables are a ...

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

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.

Lattice Gauge Fixing, Gribov Copies and BRST Symmetry [PDF]
, 1998 We show that a modification of the BRST lattice quantization allows to circumvent an old paradox, formulated by Neuberger, related to lattice Gribov copies and non-perturbative BRST invariance.

Solving general gauge theories on inner product spaces [PDF]
, 1995 By means of a generalized quartet mechanism we show in a model independent way that a BRST quantization on an inner product space leads to physical states of the form |ph>=e^{[Q, \psi]} |ph>_0 where Q is the nilpotent BRST operator, \psi a hermitian ...

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 ...

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.

Local superfield Lagrangian BRST quantization [PDF]
Journal of Mathematical Physics, 2005 A θ-local formulation of superfield Lagrangian quantization in non-Abelian hypergauges is proposed on the basis of an extension of general reducible gauge theories to special superfield models with a Grassmann parameter θ. We solve the problem of describing the quantum action and the gauge algebra of an L-stage-reducible superfield model in terms of a ...

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
