New geometric version of quantum field theory

[sas3]

The new geometric version of quantum field theory could also facilitate the search for a theory of quantum gravity that would seamlessly connect the large- and small-scale pictures of the universe

The intuitive argument that locality and unitarity must break down at some point is not very convincing, even though I find the conclusion plausible.

Let's keep talk in here technical.

From what I understand, there's no paper yet about this.

Here is a video from SUSY 2013:

Here are slides regarding the Amplituhedron (Jaroslav Trnka):

Here's two papers by Arkani-Hamed about the positive grassmanian. They're beyond me, but maybe someone else will understand

Scattering Amplitudes and the Positive Grassmannian

Local Spacetime Physics from the Grassmannian
