Simplified D = 11 pure spinor b ghost

Journal of High Energy Physics, 2017
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 ...

Finite BRST–antiBRST transformations in Lagrangian formalism

Physics Letters B, 2014
We continue the study of finite BRST–antiBRST transformations for general gauge theories in Lagrangian formalism initiated in [1], with a doublet λa, a=1,2, of anticommuting Grassmann parameters, and find an explicit Jacobian corresponding to this change

Lie algebroids and the geometry of off-shell BRST

Nuclear Physics B, 2021
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

Local operator algebras of charged states in gauge theory and gravity

Journal of High Energy Physics
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

Classical statistical simulation of quantum field theory

Journal of High Energy Physics
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.

Functional Schroedinger and BRST Quantization of (1+1)--Dimensional Gravity

, 1996
We discuss the quantization of pure string--inspired dilaton--gravity in $(1+1)$--dimensions, and of the same theory coupled to scalar matter. We perform the quantization using the functional Schroedinger and BRST formalisms.

Re-parameterization invariance of FRW model: Supervariable and BRST approaches

Nuclear Physics B
We perform the Becchi-Rouet-Stora-Tyutin (BRST) quantization of a (0+1)-dimensional cosmological Friedmann-Robertson-Walker (FRW) model. This quantization leverages the classical infinitesimal and continuous re-parameterization symmetry transformations ...

Families of gauge conditions in BV formalism

Journal of High Energy Physics, 2017
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.

Schwinger-Dyson equation for non-Lagrangian field theory

, 2006
A method is proposed of constructing quantum correlators for a general gauge system whose classical equations of motion do not necessarily follow from the least action principle. The idea of the method is in assigning a certain BRST operator $\hat\Omega$
