It's a popular science talk, not a presentation of a specific research result. The re-interpretation of scattering amplitudes in terms of novel mathematical structures is almost its own subfield of theoretical particle physics. Most of the specific results he mentioned are described in this paper: https://arxiv.org/abs/1312.2007

The 'Amplituhedron': https://arxiv.org/pdf/1312.2007.pdf The idea is to focus on the amplitude of scattering interactions from the momentum-space twistor perspective, rather than perturbations about a point in space-time. For background: Nima made a name for himself by greatly simplifying complex particle interactions, from tens of pages of Feynman diagrams to around a page. I think of the above as an extension of that project. However, I don't recall all the details, as it's been six years since I went to his talk on this.

Glad you posted this but that article is a bit user-hostile even for math wikipedia. The relevant paper is relatively approachable if you're a mathematical tourist. https://arxiv.org/pdf/1312.2007.pdf
