A pure spinor twistor description of the D = 10 superparticle
Journal of High Energy Physics, 2020 We present a novel twistor formulation of the ten-dimensional massless super-particle. This formulation is based on the introduction of pure spinor variables through a field redefinition of another model for the superparticle, and in the new description ...

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.

Annalen der Physik, Volume 537, Issue 9, September 2025.Applications of the Dressing Field Method are reviewed and further expanded to the very foundations of the supersymmetric framework, where it allows to build relational supersymmetric field theory. Furthermore, a novel approach is proposed giving a unified description of fermionic matter fields and bosonic gauge fields: a Matter‐Interaction ...

Proca theory from the spinning worldline
Journal of High Energy Physics, 2022 We obtain Proca field theory from the quantisation of the N $$ \mathcal{N} $$ = 2 supersymmetric worldline upon supplementing the graded BRST-algebra with an extra multiplet of oscillators.

Functorial constructions related to double Poisson vertex algebras
Journal of the London Mathematical Society, Volume 112, Issue 3, September 2025.Abstract For any double Poisson algebra, we produce a double Poisson vertex algebra using the jet algebra construction. We show that this construction is compatible with the representation functor which associates to any double Poisson (vertex) algebra and any positive integer a Poisson (vertex) algebra.

Constrained BRST-BFV Lagrangian formulations for higher spin fields in Minkowski spaces
Journal of High Energy Physics, 2018 BRST-BFV method to construct constrained Lagrangian formulations for (ir)reducible half-integer higher-spin Poincare group representations in Minkowski space is suggested.

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 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 ...

Symmetries in the Hamiltonian Formulation of String Theory
Advances in High Energy Physics, Volume 2025, Issue 1, 2025.In the context of the Hamiltonian formulation of string theory, a widely acknowledged issue is the inability of the first‐class constraints to accurately reproduce the Lagrangian symmetry transformations. We take a critical look at the Hamiltonian formulation of the Polyakov string and demonstrate, using Castellani′s procedure, that diffeomorphism and ...
