Lagrangian Insertion in the Light-Like Limit and the Super-Correlators/Super-Amplitudes Duality

Understand

In these notes we describe how to formulate the Lagrangian insertion technique in a way that mimics generalized unitarity.

• We introduce a notion of cuts in real space and show that the cuts of the correlators in the super-correlators/super-amplitudes duality correspond to generalized unitarity cuts of the equivalent amplitudes.
• The cuts consist of correlation functions of operators in the chiral part of the stress-tensor multiplet as well as other half-BPS operators.
• We will also discuss the application of the method to other correlators as well as non-planar contributions.
