Correlation functions of the chiral stress-tensor multiplet in N = 4 $$ \mathcal{N}=4 $$ SYM
We give a new method for computing the correlation functions of the chiral part of the stress-tensor supermultiplet that relies on the reformulation of N=4 SYM in twistor space. It yields the correlation functions in the Born approximation as a sum of Feynman diagrams on twistor space that involve only …
