Constraints, conserved charges and extended BRST algebra for a 3D field-theoretic example for Hodge theory

Nuclear Physics B
We perform the constraint analysis of a three (2 + 1)-dimensional (3D) field-theoretic example for Hodge theory (i) at the classical level within the ambit of Lagrangian formulation, and (ii) at the quantum level within the framework of Becchi-Rouet ...

Covariant Quantization with Extended BRST Symmetry [PDF]

arXiv, 1999
A short rewiev of covariant quantization methods based on BRST-antiBRST symmetry is given. In particular problems of correct definition of Sp(2) symmetric quantization scheme known as triplectic quantization are considered.

Holography as homotopy

Journal of High Energy Physics
We give an interpretation of holography in the form of the AdS/CFT correspondence in terms of homotopy algebras. A field theory such as a bulk gravity theory can be viewed as a homotopy Lie or L ∞ algebra. We extend this dictionary to theories defined on

L ∞ -algebras and the perturbiner expansion

Journal of High Energy Physics, 2019
Certain classical field theories admit a formal multi-particle solution, known as the perturbiner expansion, that serves as a generating function for all the tree-level scattering amplitudes and the Berends-Giele recursion relations they satisfy. In this

The BRST quantization of the nonlinear WB2 and W4 algebras [PDF]

Nuclear Physics B, 1994
We construct the BRST operator for the nonlinear $WB_2$ and $W_4$ algebras. Contrary to the general belief, the nilpotent condition of the BRST operator doesn't determine all the coefficients. We find a three and seven parameter family of nilpotent BRST operator for $WB_2$ and $W_4$ respectively.

Off-shell renormalization in the presence of dimension 6 derivative operators. Part I. General theory

Journal of High Energy Physics, 2019
The consistent recursive subtraction of UV divergences order by order in the loop expansion for spontaneously broken effective field theories with dimension-6 derivative operators is presented for an Abelian gauge group.

Combinatorial proof of a non-renormalization theorem

Journal 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
