The 4d/2d correspondence in twistor space and holomorphic Wilson lines
Wei Bu, Eduardo Casali
We give an explicit realization of the 4d local operator / 2d conformal block correspondence of Costello and Paquette in the case of gauge theories. This is accomplished by lifting…

Infrared behaviour of the one-loop scattering equations and supergravity integrands
Eduardo Casali, Piotr Tourkine
The recently introduced ambitwistor string led to a striking proposal for one-loop maximal supergravity amplitudes, localised on the solutions of the ambitwistor one-loop scatterin…

Soft sub-leading divergences in Yang-Mills amplitudes
Eduardo Casali
In this short note I show that the soft limit for colour-ordered tree-level Yang-Mills amplitudes contains a sub-leading divergent term analogous to terms found recently by Cachazo…
