Time evolution in general gauge theories defined on inner product spaces
, 1996 As previously shown BRST singlets |s> in a BRST quantization of general gauge theories on inner product spaces may be represented in the form |s>=e^{[Q, \psi]} |\phi> where |\phi> is either a trivially BRST invariant state which only depends on the ...

Christ–Lee Model: Augmented Supervariable Approach
Advances in High Energy Physics, Volume 2018, Issue 1, 2018., 2018 We derive the complete set of off‐shell nilpotent and absolutely anticommuting (anti‐)BRST as well as (anti‐)co‐BRST symmetry transformations for the gauge‐invariant Christ–Lee model by exploiting the celebrated (dual‐)horizontality conditions together with the gauge‐invariant and (anti‐)co‐BRST invariant restrictions within the framework of ...

On gauge fixing in the Lagrangian formalism of superfield BRST quantization
, 1999 We propose a modification of the gauge-fixing procedure in the Lagrangian method of superfield BRST quantization for general gauge theories which simultaneously provides a natural generalization of the well-known BV quantization scheme as far as gauge ...

Tensionless p-branes with manifest conformal invariance [PDF]
, 1997 The quantization of the tensionless p-brane is discussed. Inspection of the constraint algebra reveals that the central extensions for the p-branes have a simple form.

Loop Amplitudes and Quantum Homotopy Algebras
Journal of High Energy Physics, 2020 We derive a recursion relation for loop-level scattering amplitudes of La- grangian field theories that generalises the tree-level Berends-Giele recursion relation in Yang-Mills theory.

Taming the 11D pure spinor b-ghost
Journal of High Energy Physics, 2023 We provide an alternative compact expression for the 11D pure spinor b-ghost by introducing a new set of negative ghost number operators made out of non-minimal pure spinor variables.

On the Covariant Quantization of the 2nd-Ilk Superparticle
, 1991 This paper is devoted to the quantization of the second-ilk superparticle using the Batalin-Vilkovisky method. We show the full structure of the master action.

The quantum theory of Chern-Simons supergravity
Journal of High Energy Physics, 2019 We consider AdS 3 N-extended Chern-Simons supergravity (à la Achucarro-Townsend) and we study its gauge symmetries. We promote those gauge symmetries to a BRST symmetry and we perform its quantization by choosing suitable gauge-fixings.

On the geometric quantization and BRST quantization for bosonic strings
Physics Letters B, 1989 Abstract The complex geometry and the geometric quantization for bosonic strings are discussed. It is found that the conformal anomalies in the holomorphic and anti-holomorphic Fock spaces may be interpreted as curvatures of the holomorphic and anti-holomorphic Fock bundles on G″ = G/H.

Relating the Green-Schwarz and Pure Spinor Formalisms for the Superstring
, 2004 Although it is not known how to covariantly quantize the Green-Schwarz (GS) superstring, there exists a semi-light-cone gauge choice in which the GS superstring can be quantized in a conformally invariant manner.
