Auxialiary conditions in BRST quantization

open access: yesNuclear Physics B, 1992
Abstract A general structure of allowed auxiliary conditions in both ordinary and generalized BRST quantization is presented. Such conditions are shown to fall into two classes which always should imply each other. Both antiBRST invariance and coBRST invariance are shown to fit into the framework.

Combinatorial proof of a non-renormalization theorem

open access: yesJournal of High Energy Physics
We provide a direct combinatorial proof of a Feynman graph identity which implies a wide generalization of a formality theorem by Kontsevich. For a Feynman graph Γ, we associate to each vertex a position x v ∈ ℝ and to each edge e the combination s e = a

A ∞ action of open $$\mathcal{N}=2$$ superstring field theory

open access: yesJournal of High Energy Physics
We formulate a string field theory for open $$\mathcal{N}=2$$ strings with an A ∞ algebra structure. Starting from the BRST cohomology relative to the U(1) anti-ghost zero-mode, we generalize [arXiv:1312.2948] and constructed all interacting vertices ...

BRST quantization of the superparticle

open access: yesPhysics 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
