Abstract

摘要

I will give a basic introduction to modern methods for computing and understanding scattering amplitudes, which are of increasing importance for both phenomenological applications in particle physics, and fundamental aspects of QFT and string theory. In these first two lectures, I will review color decomposition, spinor-helicity formalism, tree-level BCFW recursions and (briefly) on-shell methods for loop amplitudes.
