The ${\cal N}=4$ Supergravity NMHV six-point one-loop amplitude

High Energy Physics - Theory 2017-01-04 v3

Abstract

We construct the six-point NMHV one-loop amplitude in N=4{\cal N}=4 supergravity using unitarity and recursion. The use of recursion requires the introduction of rational descendants of the cut-constructible pieces of the amplitude and the computation of the non-standard factorisation terms arising from the loop integrals.
