Massive gravity from a first-quantized perspective
In this work, we investigate the BRST quantization of the massive $${\mathcal {N}}=4$$ N = 4 supersymmetric spinning particle, with a twofold purpose: exploring different approaches to give mass to spinning particle models and formulating a first ...

Families of gauge conditions in BV formalism
In BV formalism we can consider a Lagrangian submanifold as a gauge condition. Starting with the BV action functional we construct a closed form on the space of Lagrangian submanifolds.

Lie algebroids and the geometry of off-shell BRST
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

Four approaches to quantization of the relativistic particle [PDF]
The connection between four different approaches to quantization of the relativistic particle is studied: reduced phase space quantization, Dirac quantization, BRST quantization, and (BRST)-Fock quantization are each carried out. The connection to the BFV path integral in phase space is provided.

Local operator algebras of charged states in gauge theory and gravity
Powerful techniques have been developed in quantum field theory that employ algebras of local operators, yet local operators cannot create physical charged states in gauge theory or physical nonzero-energy states in perturbative quantum gravity. A common

Simplified D = 11 pure spinor b ghost
A b-ghost was constructed for the D = 11 non-minimal pure spinor superparticle by requiring that {Q, b} = T where Q = Λ α D α + R α W ¯ α $$ Q={\Lambda}^{\alpha }{D}_{\alpha }+{R}^{\alpha }{\overline{W}}_{\alpha } $$ is the usual non-minimal pure spinor ...

Classical statistical simulation of quantum field theory
We propose a procedure of computing the n-point function in perturbation theory of the quantum field theory as the average over the complex Gaussian noises in a classical theory.

BRST operator quantization of generally covariant gauge systems
The BRST generator is realized as a Hermitian nilpotent operator for a finite-dimensional gauge system featuring a quadratic super-Hamiltonian and linear supermomentum constraints.
