Abstract

The action of holomorphic inverse soft factors on scattering amplitudes in N=4 SYM is shown to take a remarkably simple form in momentum twistor space. This is used to identify individual residues of the grassmannian with primitive leading singularities at NMHV and N2MHV and to derive explicit expressions in terms of momentum twistors.
