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.

Superfield lagrangian quantization with extended BRST symmetry [PDF]
Physics Letters B, 2001 We consider possible superfield representations of extended BRST symmetry for general gauge theories within the principle of gauge-fixing based on a generating equation for the gauge functional. We examine admissible superfield choices for an extended antibracket and delta-operator with given algebraic properties and show that only one of these choices

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

On the BPS Sector in AdS3/CFT2 Holography
Fortschritte der Physik, Volume 71, Issue 4-5, May 2023., 2023 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.

Homotopy Transfer and Effective Field Theory II: Strings and Double Field Theory
Fortschritte der Physik, Volume 70, Issue 2-3, March 2022., 2022 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
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.
