Spin fields for the spinning particle
Journal of High Energy Physics, 2022 We propose an analogue of spin fields for the relativistic RNS-particle in 4 dimensions, in order to describe Ramond-Ramond states as “two-particle” excitations on the world line.

Exploring T‐Duality for Self‐Dual Fields
Fortschritte der Physik, Volume 72, Issue 5, May 2024.Abstract Avatars of T‐duality within Sen's formalism for self‐dual field strengths in various dimensions are studied. This formalism is shown to naturally accommodate the T‐duality relation between Type IIA/IIB theories when compactified on a circle without the need for imposing the self‐duality constraint by hand, as is usually done. The study of this

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.

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 quantization of noncommutative gauge theories [PDF]
Physical Review D, 2003 In this paper, the BRST symmetry transformation is presented for the noncommutative U(N) gauge theory. The nilpotency of the charge associated to this symmetry is then proved. As a consequence for the space-like non-commutativity parameter, the Hilbert space of physical states is determined by the cohomology space of the BRST operator as in the ...

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.

Massive gravity from a first-quantized perspective
European Physical Journal C: Particles and FieldsIn this work, we investigate the BRST quantization of the massive $${\mathcal {N}}=4$$ N = 4 supersymmetric spinning particle, with a twofold purpose: exploring different approaches to give mass to spinning particle models and formulating a first ...

BRST quantization of the superparticle
Physics Letters B, 1988 Abstract We show that the quantization of the superparticle action is possible. This is done by shifts in the BRST operator and the resulting action has an infinite number of ghosts. The total BRST operator is given by an infinite sum and is shown to be nilpotent. We also obtain a BRST invariant kinetic operator that contains the dynamical, auxiliary
