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 ...

The one-loop unimodular graviton propagator in any dimension
Journal of High Energy Physics, 2023 For unimodular gravity, we work out, by using dimensional regularization, the complete one-loop correction to the graviton propagator in any space-time dimension.

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.

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 ...

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.

On the Irreducible BRST Quantization of Spin-5/2 Gauge Fields [PDF]
Class.Quant.Grav. 15 (1998) 501-507, 1999 Spin-5/2 gauge fields are quantized in an irreducible way within both the BRST and BRST-anti-BRST manners. To this end, we transform the reducible generating set into an irreducible one, such that the physical observables corresponding to these two formulations coincide.

Towards an M5‐Brane Model II: Metric String Structures
Fortschritte der Physik, Volume 68, Issue 8, August 2020., 2020 Abstract In this paper, we develop the mathematical formulation of metric string structures. These play a crucial role in the formulation of certain six‐dimensional superconformal field theories and we believe that they also underlie potential future formulations of the (2,0)‐theory. We show that the connections on non‐abelian gerbes usually introduced

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

Massive Spinning Relativistic Particle: Revisited under BRST and Supervariable Approaches
Advances in High Energy Physics, Volume 2020, Issue 1, 2020., 2020 We discuss the continuous and infinitesimal gauge, supergauge, reparameterization, nilpotent Becchi‐Rouet‐Stora‐Tyutin (BRST), and anti‐BRST symmetries and derive corresponding nilpotent charges for the one (0 + 1)‐dimensional (1D) massive model of a spinning relativistic particle.
