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 ...

Gauged Floreanini-Jackiw type chiral boson and its BRST quantization [PDF]
, 2016 The gauged model of Siegel type chiral boson is considered. It has been shown that the action of gauged model of Floreanini-Jackiw (FJ) type chiral boson is contained in it in an interesting manner.

A SUPERSPACE FORMULATION FOR THE BATALIN VILKOVISKY FORMALISM WITH EXTENDED BRST INVARIANCE [PDF]
, 1995 A superspace formulation for the Batalin Vilkovisky formalism (also called field-antifield quantization ) with extended BRST invariance (BRST and anti-BRST invariance ) for gauge theories with closed algebra is presented.

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.

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 ...

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.

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

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.

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.

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 ...
