De Sitter Light-Ray Operators
Shounak De, Yakov Landau
In this work, we initiate the study of light-ray operators in four-dimensional de Sitter space focusing on null integrals of the stress tensor. In Minkowski space, the null integra…

Spinning dispersive CFT sum rules and bulk scattering
Cyuan-Han Chang, Yakov Landau, David Simmons-Duffin
We use commutativity of null-integrated operators on the same null plane to construct dispersive CFT sum rules for spinning operators. The contribution of heavy blocks to these sum…
