A SUPERSPACE FORMULATION FOR THE BATALIN VILKOVISKY FORMALISM WITH EXTENDED BRST INVARIANCE [PDF]
, 1995 A superspace formulation for the Batalin Vilkovisky formalism (also called field-antifield quantization ) with extended BRST invariance (BRST and anti-BRST invariance ) for gauge theories with closed algebra is presented.

Principles of BRST quantization
Nuclear Physics B, 1989 Abstract The BRST quantization as a quantization method ised. It is pointed out that all formal manipulations are only valid if all inner products in the original state space are finite. This restriction is also shown to be necessary in order to obtain the correct results for trivial models.

Towards an M5‐Brane Model II: Metric String Structures
Fortschritte der Physik, Volume 68, Issue 8, August 2020., 2020 Abstract In this paper, we develop the mathematical formulation of metric string structures. These play a crucial role in the formulation of certain six‐dimensional superconformal field theories and we believe that they also underlie potential future formulations of the (2,0)‐theory. We show that the connections on non‐abelian gerbes usually introduced

Stability and Hamiltonian BRST-invariant deformations in Podolsky's generalized electrodynamics
Nuclear Physics B, 2021 We study the problem of stability in Podolsky's generalized electrodynamics by constructing a series of 2-parametric bounded conserved quantities. In this way, we show that the 00-component of the energy-momentum tensors could be positive definite and ...

Braided quantum electrodynamics
Journal of High Energy Physics, 2023 The homotopy algebraic formalism of braided noncommutative field theory is used to define the explicit example of braided electrodynamics, that is, U(1) gauge theory minimally coupled to a Dirac fermion.

Massive Spinning Relativistic Particle: Revisited under BRST and Supervariable Approaches
Advances in High Energy Physics, Volume 2020, Issue 1, 2020., 2020 We discuss the continuous and infinitesimal gauge, supergauge, reparameterization, nilpotent Becchi‐Rouet‐Stora‐Tyutin (BRST), and anti‐BRST symmetries and derive corresponding nilpotent charges for the one (0 + 1)‐dimensional (1D) massive model of a spinning relativistic particle.

Modified 2D Proca Theory: Revisited under BRST and (Anti‐)chiral Superfield Formalisms
Advances in High Energy Physics, Volume 2020, Issue 1, 2020., 2020 Within the framework of Becchi‐Rouet‐Stora‐Tyutin (BRST) approach, we discuss mainly the fermionic (i.e., off‐shell nilpotent) (anti‐)BRST, (anti‐)co‐BRST, and some discrete dual symmetries of the appropriate Lagrangian densities for a two (1 + 1)‐dimensional (2D) modified Proca (i.e., a massive Abelian 1‐form) theory without any interaction with ...

BRST quantization and equivariant cohomology: localization with asymptotic boundaries
Journal of High Energy Physics, 2018 We develop BRST quantization of gauge theories with a soft gauge algebra on spaces with asymptotic boundaries. The asymptotic boundary conditions are imposed on background fields, while quantum fluctuations about these fields are described in terms of ...
