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.

BRST invariance and de Rham-type cohomology of 't Hooft-Polyakov monopole
, 2009 We exploit the 't Hooft-Polyakov monopole to define closed algebra of the quantum field operators and the BRST charge $Q_{BRST}$. In the first-class configuration of the Dirac quantization, by including the $Q_{BRST}$-exact gauge fixing term and the ...

BRST Formalism and Zero Locus Reduction [PDF]
, 2000 In the BRST quantization of gauge theories, the zero locus $Z_Q$ of the BRST differential $Q$ carries an (anti)bracket whose parity is opposite to that of the fundamental bracket.

Irreducible Hamiltonian BRST symmetry for reducible first-class systems
, 2000 An irreducible Hamiltonian BRST quantization method for reducible first-class systems is proposed. The general theory is illustrated on a two-stage reducible model, the link with the standard reducible BRST treatment being also emphasized.Comment: Latex ...

BRST quantization in the Siegel gauge
Physics Letters B, 1987 From a formal generalization to N copies of the free open string field theory BRST-quantized in the Siegel gauge we reproduce the BRST quantization of the free closed bosonic string field theory and obtain the one of massless higher spin field theories.

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.

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.

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.

Nuclear Physics B, 1987 Abstract A quantum gauge theory is anomalous within the BRST quantization if there does not exist any conserved, nilpotent BRST charge. What is to be called the BRST charge is then either a nilpotent of a conserved charge. It is proposed that a particular conserved charge may be used to consistently quantize an anomalous gauge theory.

The algebraic structure of BRST quantization
Physics Letters B, 1986 Abstract It is shown that a system of first-class bosonic constraints obeying a Lie algebra has associated with it a natural superalgebra. BRST quantization arises as a non-linear representation of this superalgebra. Two distinct superalgebras are explicitly constructed and their associated BRST quantizations presented. The first BRST quantization is
