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…
Visions in Quantum Gravity
Luca Buoninfante, Benjamin Knorr, K. Sravan Kumar +36
To deepen our understanding of Quantum Gravity and its connections with black holes and cosmology, building a common language and exchanging ideas across different approaches is cr…
Causality Bounds on the Primordial Power Spectrum
Mariana Carrillo González, Sebastián Céspedes
Effective field theories (EFTs) parametrize our ignorance of the underlying UV theory through their Wilson coefficients. However, not all values of these coefficients are consisten…
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…
