4d CFT Correlators from Ambitwistors
Mariana Carrillo González, Théo Keseman
We develop an ambitwistor-space formulation of conserved spinning correlators in four-dimensional CFTs. We show that conformal symmetry and conservation are trivialised by the ambi…

Spinning Boundary Correlators from (A)dS Twistors
Mariana Carrillo González, Théo Keseman
We develop a twistor-space framework to compute boundary correlators via a boundary limit of nested Penrose transforms in (A)dS. Starting from correlators of (anti-)self-dual b…

Double Copy in AdS3 from Minitwistor Space
Cameron Beetar, Mariana Carrillo González, Sumer Jaitly +1
The double copy relates gravitational theories to the square of gauge theories. While it is well understood in flat backgrounds, its precise realisation around curved spacetimes re…
