Ambitwistor strings and amplitudes in curved backgrounds

Abstract:

Feynman diagrams have been superseded as the tool of choice for calculating scattering amplitudes. Various other methods are not only more efficient but also explicitly exhibit beautiful structures obscured by Feynman diagrams. This thesis aims to lay some groundwork on how two of these methods, ambitwistor strings and the double copy, can be generalised to scattering in curved backgrounds.

In the first part of this thesis, a heterotic ambitwistor string model coupled to a non-abeli...
