These are my notes on the "Amplitudes" course taught at Durham University in 2020.
The course presents scatting amplitude calculations from a modern, spinor-helicity, formalism. In particular we focus on spin-1 purely gluonic amplitudes. The Parke-Taylor formula for MHV amplitudes and the BCFW recursion relation are derived.
By presenting amplitudes in this way, we highlight underlying symmetries that are non-manifest in the Feynman diagram approach.
The course was taught over 4 weeks and lasted 8 hours.
