All-Loop Order Negative Geometries for Planar N=4 SYM Amplitudes
Abstract: In this talk, I will review a recent progress on the use of the Amplituhedron construction to calculate four-point scattering amplitudes in the planar N=4 SYM theory. This uses a novel expansion of the loop integrand using negative geometries which make manifest the IR properties of the final answer. In certain cases, this expansion can be resumed to all loop orders providing a certain approximation of the full non-perturbative amplitude.
