Description |
Starting with the seminal work of Arkani-Hamed et al., there has been growing evidence of an intriguing relationship between the geometry of certain class of Polytopes and scattering amplitudes of massless scalar particles. This new perspective on scattering amplitude aims to reconfigure the fundamental postulates of S-matrix theory. A principle called Projectivity becomes primary and leads to unitarity and locality of the S matrix. In this talk, I will review the key ideas of Arkani-Hamed et al. in the context of the tree-level S matrix of massless φ |
