A brief introduction to modern amplitude methods

By L. Dixon. 2013

145 citations recorded by the source corpus.

I provide a basic introduction to modern helicity amplitude methods, including color organization, the spinor helicity formalism, and factorization properties. I also de- scribe the BCFW (on-shell) recursion relation at tree level, and explain how similar ideas — unitarity and on-shell methods — work at the loop level. These notes are based on lectures delivered at the 2012 CERN Summer School and at TASI 2013.
