Hidden properties of non-planar amplitudes in N=4 SYM
Enrico Herrmann (Caltech)

Scattering amplitudes in planar 𝑁 = 4 SYM have many interesting properties: dual con- formal and Yangian symmetries, connection to Wilson loops and integrability, formula- tion using on-shell diagrams, positive Grassmannian and Amplituhedron. None of them is true when we go beyond the planar limit. I will show that quite surprisingly the non planar amplitudes still posses the same properties as their planar counterparts suggesting the existence of hidden symmetries and new formulations in the complete 𝑁 = 4 SYM.
