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 ...

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 ...

Irreducible antifield-BRST approach to reducible gauge theories [PDF]
, 1999 An irreducible antifield BRST quantization method for reducible gauge theories is proposed. The general formalism is illustrated in the case of the Freedman-Townsend model.Comment: 19 pages, LaTeX 2 ...

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.

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 ...

BRST-BV quantization of gauge theories with global symmetries
European Physical Journal C: Particles and Fields, 2018 We consider the general gauge theory with a closed irreducible gauge algebra possessing the non-anomalous global (super)symmetry in the case when the gauge fixing procedure violates the global invariance of classical action.

On the canonical formulation of gauge field theories and Poincaré transformations
Nuclear Physics B, 2021 We address the Hamiltonian formulation of classical gauge field theories while putting forward results some of which are not entirely new, though they do not appear to be well known.

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 ...

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.

Pseudoscalar Field as a Possible Candidate for Phantom Field
Advances in High Energy Physics, Volume 2025, Issue 1, 2025.We demonstrate the existence of a single pseudoscalar (PS) field in the mathematically backed and parity‐preserving modifications of the standard Stückelberg formalism (SSF) in the context of the Lagrangian formulation of the (i) two (1 + 1)‐dimensional (2D) massive Abelian 1‐form gauge theory, (ii) three (2 + 1)‐dimensional (3D) massive Abelian 2‐form
