简介: |
摘要：This talk will provide a brief review of the ongoing S matrix program. In particular, I will show how the BCFW recursion relation arises. Then employing Penrose's twistor programme I will demonstrate how 3-point scattering amplitude can be exactly determined by Poincare symmetry and why n-point scattering amplitude can be obtained through the BCFW recursion relation without local quantum field theory.
