Hamiltonian and Lagrangian BRST Quantization in Riemann Manifold
Advances in High Energy Physics, 2022 The BRST quantization of particle motion on the hypersurface VN−1 embedded in Euclidean space RN is carried out both in Hamiltonian and Lagrangian formalism. Using Batalin-Fradkin-Fradkina-Tyutin (BFFT) method, the second class constraints obtained using

Reparameterization Invariant Model of a Supersymmetric System: BRST and Supervariable Approaches
Advances in High Energy Physics, 2021 We carry out the Becchi-Rouet-Stora-Tyutin (BRST) quantization of the one 0+1-dimensional (1D) model of a free massive spinning relativistic particle (i.e., a supersymmetric system) by exploiting its classical infinitesimal and continuous ...

BRST quantization and equivariant cohomology: localization with asymptotic boundaries [PDF]
Journal of High Energy Physics, 2018 We develop BRST quantization of gauge theories with a soft gauge algebra on spaces with asymptotic boundaries. The asymptotic boundary conditions are imposed on background fields, while quantum fluctuations about these fields are described in terms of ...

BFV quantization and BRST symmetries of the gauge invariant fourth-order Pais-Uhlenbeck oscillator
Nuclear Physics B, 2022 We perform the BFV-BRST quantization of the fourth-order Pais-Uhlenbeck oscillator (PUO) for the first time. We show that although the PUO is not naturally constrained in the sense of Dirac-Bergmann, it is possible to profit from the introduction of ...

Stability and Hamiltonian BRST-invariant deformations in Podolsky's generalized electrodynamics
Nuclear Physics B, 2021 We study the problem of stability in Podolsky's generalized electrodynamics by constructing a series of 2-parametric bounded conserved quantities. In this way, we show that the 00-component of the energy-momentum tensors could be positive definite and ...

BRST supergroups and quantization [PDF]
Physics Letters B, 1989 Abstract We construct the smallest supergroup (K) containing among its generators those of a constraint subgroup K, the BRST charge and the corresponding ghost and antighost operators. When K is diffS1 the critical dimension of string theory can be interpreted as a singularity in the carrier space for the irreducible representations of the ...

Geometric BRST quantization, I: Prequantization [PDF]
Communications in Mathematical Physics, 1991 The problem of defining formally the procedure of BRST quantization, which has become the preferred method to quantize gauge systems, is considered. In defining the BRST quantization it seems natural to exploit the symplectic nature of classical BRST. Therefore authors focus their attention in the method of geometric quantization.

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.

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 ...

Constraints, symmetry transformations and conserved charges for massless Abelian 3-form theory
Nuclear Physics B, 2023 We demonstrate the existence of the first-class constraints on the massless Abelian 3-form theory which generate the classical gauge symmetry transformations for this theory in any arbitrary D-dimension of spacetime. We write down the explicit expression
