Description (deu)

Carrollian amplitudes are massless scattering amplitudes expressed in position space at null infinity. These are to be re-interpreted as correlation functions in a putative dual Carrollian CFT. I will discuss the properties of Carrollian amplitudes and their relations with celestial amplitudes. I will explain how the collinear limit unveils a notion of Carrollian OPE and deduce the action of celestial symmetries at null infinity. Finally, I will present a direct connection between twistor space and Carrollian amplitudes. Based on arxiv.org/abs/2312.10138.
