Carrollian Amplitudes, Celestial Symmetries and Twistor Space

Explore Carrollian amplitudes, celestial symmetries, and twistor space in this comprehensive conference talk. Delve into the properties of Carrollian amplitudes and their relationship with celestial amplitudes. Discover how the collinear limit reveals a concept of Carrollian OPE and learn about the action of celestial symmetries at null infinity. Examine the direct connection between twistor space and Carrollian amplitudes. Based on research from https://arxiv.org/abs/2312.10138, this talk was presented as part of the Thematic Programme on "Carrollian Physics and Holography" at the Erwin Schrödinger International Institute for Mathematics and Physics (ESI) in April 2024.
