Proof of the MHV vertex expansion for all tree amplitudes in N=4 SYM theory
Henriette Elvang, Daniel Z. Freedman, Michael Kiermaier
We prove the MHV vertex expansion for all tree amplitudes of N=4 SYM theory. The proof uses a shift acting on all external momenta, and we show that every N^kMHV tree amplitude fal…
Recursion Relations, Generating Functions, and Unitarity Sums in N=4 SYM Theory
Henriette Elvang, Daniel Z. Freedman, Michael Kiermaier
We prove that the MHV vertex expansion is valid for any NMHV tree amplitude of N=4 SYM. The proof uses induction to show that there always exists a complex deformation of three ext…
Generating Tree Amplitudes in N=4 SYM and N=8 SG
Massimo Bianchi, Henriette Elvang, Daniel Z. Freedman
We study n-point tree amplitudes of N=4 super Yang-Mills theory and N=8 supergravity for general configurations of external particles of the two theories. We construct generating f…
