Local superfield Lagrangian BRST quantization [PDF]
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 ...

On the BPS Sector in AdS3/CFT2 Holography
Abstract The BPS sector in AdS3/CFT2$AdS_3/CFT_2$ duality has been fertile ground for the exploration of gauge/gravity duality, from the match between black hole entropy and the CFT elliptic genus to the construction of large families of geometrical microstates and the identification of the corresponding states in the CFT.

Constraints, symmetry transformations and conserved charges for massless Abelian 3-form theory
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

Homotopy Transfer and Effective Field Theory II: Strings and Double Field Theory
Abstract We continue our study of effective field theory via homotopy transfer of L∞$L_\infty$‐algebras, and apply it to tree‐level non‐Wilsonian effective actions of the kind discussed by Sen in which the modes integrated out are comparable in mass to the modes that are kept. We focus on the construction of effective actions for string states at fixed

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

BRST quantization of matrix models with constraints and two-dimensional Yang-Mills theory on the cylinder [PDF]
BRST quantization of the one-dimensional constrained matrix model which describes two-dimensional Yang-Mills theory on the cylinder is performed. Classical and quantum BRST generators and BRST-invariant hamiltonians are constructed. Evolution operator is

Nilpotent Symmetries of a Model of 2D Diffeomorphism Invariant Theory: BRST Approach
Within the framework of the Becchi‐Rouet‐Stora‐Tyutin (BRST) formalism, we discuss the full set of proper BRST and anti‐BRST transformations for a 2D diffeomorphism invariant theory which is described by the Lagrangian density of a standard bosonic string. The above (anti‐)BRST transformations are off‐shell nilpotent and absolutely anticommuting.

Superfield Approaches to a Model of Bosonic String: Curci‐Ferrari‐Type Restrictions
Exploiting the theoretical potential of the modified Bonora‐Tonin superfield approach (MBTSA) as well as the (anti‐)chiral superfield approach (ACSA) to Becchi‐Rouet‐Stora‐Tyutin (BRST) formalism, we derive the complete set of off‐shell nilpotent (anti‐)BRST symmetry transformations corresponding to the classical two‐ (1 + 1) dimensional (2D ...

Lattice Gauge Fixing, Gribov Copies and BRST Symmetry [PDF]
We show that a modification of the BRST lattice quantization allows to circumvent an old paradox, formulated by Neuberger, related to lattice Gribov copies and non-perturbative BRST invariance.

Double Copy from Homotopy Algebras
It will be shown that the BRST Lagrangian double copy construction of N = 0 supergravity as the ‘square’ of Yang–Mills theory finds a natural interpretation in terms of homotopy algebras. The authors significantly expand on their previous work arguing the validity of the double copy at the loop level, and they give a detailed derivation of the double ...
