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.

Gauge-invariant spectral description of the U (1) Higgs model from local composite operators

Journal of High Energy Physics, 2020
The spectral properties of a set of local gauge-invariant composite operators are investigated in the U(1) Higgs model quantized in the ’t Hooft R ξ gauge.

BRST quantization of gauge theory in noncommutative geometry: Matrix derivative approach [PDF]

, 1995
The Becchi–Rouet–Stora–Tyutin (BRST) quantization of a gauge theory in noncommutative geometry is carried out in the ‘‘matrix derivative’’ approach.

KPZ Analysis for $W_3$ Gravity

, 1992
Starting from the covariant action for $W_3$ gravity, we discuss the BRST quantization of $W_3$ gravity. Taking the chiral gauge the BRST charge has a natural interpretation in terms of the quantum Drinfeld--Sokolov reduction for $Sl(3,\re)$.

BFV-BRST quantization of two-dimensional supergravity [PDF]

Physical Review D, 1996
Two-dimensional supergravity theory is quantized as an anomalous gauge theory. In the Batalin-Fradkin (BF) formalism, the anomaly-canceling super-Liouville fields are introduced to identify the original second-class constrained system with a gauge-fixed version of a first-class system.

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.

BRST operator quantization of generally covariant gauge systems

, 1997
The BRST generator is realized as a Hermitian nilpotent operator for a finite-dimensional gauge system featuring a quadratic super-Hamiltonian and linear supermomentum constraints.

Noncommutative Topological Half-flat Gravity

, 2004
We formulate a noncommutative description of topological half-flat gravity in four dimensions. BRST symmetry of this topological gravity is deformed through a twisting of the usual BRST quantization of noncommutative gauge theories.
