Generally when we calculate scattering amplitudes, we work with objects such as momentum and polarisation 4-vectors. However, by working directly with spinor variables the scattering amplitudes of massless particles can be expressed in very simple and symmetric forms. This is the basis of the spinor helicity formalism. The goal of my talk is to give an overview of the formalism, and if time allows I will discuss how it can be extended to deal with massive particles.
