Abstract: | Coauthor: Enrico Herrmann
There has been a lot of progress in exploring new mathematical structures in N=4 SYM amplitudes: on-shell diagrams and Amplituhedron in the planar sector, and special properties of integrands beyond the planar limit. I will review some of these developments and then focus how the similar ideas can be extended to N=8 supergravity amplitudes. As it turns out the singularity structure of supergravity amplitudes is very different and it exhibits some surprising features at both UV and IR. |
