Superprotected n-point correlation functions of local operators in N=4 super Yang-Mills

Drukker, Nadav, Plefka, Jan

Understand

In this paper we study the n-point correlation functions of two different families of local gauge invariant operators in N=4 supersymmetric Yang-Mills theory.

  • The main idea is to consider the correlation functions of operators which all share a number of supersymmetries irrespective of their relative locations.
  • We achieve this by equipping the operators with explicit space-time dependence.
  • We provide evidence by different methods that these n-point correlators do not receive quantum corrections in perturbation theory and are hence given exactly by their tree-level result.
