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…
A Worldsheet Theory for Supergravity
Tim Adamo, Eduardo Casali, David Skinner
We present a worldsheet theory that describes maps into a curved target space equipped with a B-field and dilaton. The conditions for the theory to be consistent at the quantum lev…
Perturbative gravity at null infinity
Tim Adamo, Eduardo Casali, David Skinner
We describe a theory that lives on the null conformal boundary of asymptotically flat space-time, and whose states encode the radiative modes of (super)gravity. We study the induce…
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…
