A Course in Amplitudes

Understand

This a pedagogical introduction to scattering amplitudes in gauge theories.

• It proceeds from Dirac equation and Weyl fermions to the two pivot points of current developments: the recursion relations of Britto, Cachazo, Feng and Witten, and the unitarity cut method pioneered by Bern, Dixon, Dunbar and Kosower.
• In ten lectures, it covers the basic elements of on-shell methods.
