Perturbative Super-Yang-Mills from the Topological AdS_5xS^5 Sigma Model

TL;DR

This paper explores a topological sigma model derived from the pure spinor formalism to study the small radius limit of the AdS_5xS^5 superstring, aiming to connect topological string states with super-Yang-Mills correlators.

Contribution

It introduces a novel topological sigma model framework that reproduces super-Yang-Mills correlation functions via topological amplitudes and Wilson line constructions.

Findings

Topological amplitudes match super-Yang-Mills Feynman diagrams.

States constructed from holes and Wilson lines encode gauge-invariant correlators.

Model provides a new perspective on the AdS/CFT correspondence at small radius.

Abstract

A topological sigma model based on the pure spinor formalism was recently proposed for the small radius limit of the AdS_5xS^5 superstring. Physical states in this model can be constructed by connecting holes on the worldsheet with Wilson lines of the worldsheet gauge field. The contribution of these states to the topological amplitude is claimed to reproduce the usual Feynman diagram expansion of gauge-invariant super-Yang-Mills correlation functions.
