I have a question that didn't get answered when I talked to people about amplituhedron. Do the higher k (dimension, I'm unsure) Grasmannian calculations have any bearing on a world without super symmetry. Because Nima's tool is only useful for super symmetric calculations then honestly it's not very compelling. I want to be wrong, it's very beautiful math, but it seems holy impractical for "real world" standard model physics.
- danbruc 8y agoI am a total layman, so I don't know. But if I understood it right, the nice final results relies on the use of Grassmannn variables which eventually cancel out. Whether or not there is a path to non-supersymmetric theories, I have no idea. But even if it fundamentally requires supersymmetry, the jury is still out on whether or not the universe is supersymmetric even though the best versions have now been ruled out.
