Speaker

Joe Farrow (Durham University)

Description

I will discuss how on-shell diagrams for N=4 Super Yang Mills can be extended to N=8 Supergravity, giving Grassmannian integral formulae for tree-level amplitudes. I will then describe the connection between these formulae and equivalent expressions for the same amplitudes arising from ambitwistor string theory.
