Shifting Spin on the Celestial Sphere
Sabrina Pasterski, Andrea Puhm
We explore conformal primary wavefunctions for all half integer spins up to the graviton. Half steps are related by supersymmetry, integer steps by the classical double copy. The m…
Loops on the Celestial Sphere
Hernan A. Gonzalez, Andrea Puhm, Francisco Rojas
We study the effect of loop corrections to conformal correlators on the celestial sphere at null infinity. We first analyze finite one-loop celestial amplitudes in pure Yang-Mills…
Double Copy for Celestial Amplitudes
Eduardo Casali, Andrea Puhm
Celestial amplitudes which use conformal primary wavefunctions rather than plane waves as external states offer a novel opportunity to study properties of amplitudes with manifest…
Asymptotic Symmetries and Celestial CFT
Laura Donnay, Sabrina Pasterski, Andrea Puhm
We provide a unified treatment of conformally soft Goldstone modes which arise when spin-one or spin-two conformal primary wavefunctions become pure gauge for certain integer value…
