title: Maximal-helicity-violating n-point one-loop amplitude in N=4 supergravity.
abstract: We propose an explicit formula for the n-point maximal-helicity-violating one-loop amplitude in a N=4 supergravity theory. This formula is derived from the soft and collinear factorizations of the amplitude.
