Description

The CHY technique for computing scattering amplitudes has been used in a large variety of theories ranging from Einstein gravity to the Chiral Lagrangian. Many of these theories have in common that they are effective field theories (EFTs) of spontaneously broken symmetries. In this talk I will review recent results relating these effective field theories including the recent formula for the tree level S-matrix of the ETF on a single M5-brane obtained by Heydeman, Schwarz and Wen.
