Abstract
摘要 |
Our understanding on scattering amplitudes in Gauge Theories and Gravity
was deepened a lot since Witten's significant work on twistor string theory.
The on-shell recursion relation at tree-level, found by Britto, Cachazo, Feng and Witten
around a decade ago, play a key role in this progress. This made analytic computations
of tree amplitudes much more easy.
In this talk, I will star with introduction on color decomposition, spinor helicity method
(a. k. a. Chinese magic). On-shell recursion relation will be proof in details. The talk
will end with examples on applications of this important relation. General MHV amplitudes
and 6-particle NMHV amplitudes will be computed. |
