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

Understand

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.
