Description

Cachazo, He and Yuan have produced remarkable formulae that express tree-level scattering amplitudes as sums over certain solutions to the scattering equations defined on the Riemann sphere. The lecture will explain how these formulae arise from a holomorphic string theory in ambitwistor space and will go on to explain some further developments such as soft limits and/or loop amplitudes.
