A note on NMHV form factors from the Gra{\ss}mannian and the twistor string
In this note we investigate Graßmannian formulas for form factors of the chiral part of the stress-tensor multiplet in $ \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 diagrams and the...
