A note on NMHV form factors from the Graßmannian and the twistor string

Abstract In this note we investigate Graßmannian formulas for form factors of the chiral part of the stress-tensor multiplet in N = 4 $$ \mathcal{N}=4 $$ superconformal Yang-Mills theory. We present an all-n contour for the G(3, n + 2) Graßmannian integral of NMHV form factors derived from on-shell...
