Celestial holography and AdS3/CFT2 from a scaling reduction of twistor space
Wei Bu, Sean Seet
Celestial amplitudes obtained from Mellin transforming 4d momentum space scattering amplitudes contain distributional delta functions, hindering the application of conventional CFT…
All-order celestial OPE in the MHV sector
Tim Adamo, Wei Bu, Eduardo Casali +1
On-shell kinematics for gluon scattering can be parametrized with points on the celestial sphere; in the limit where these points collide, it is known that tree-level gluon scatter…
Moyal deformations, and celestial holography
Wei Bu, Simon Heuveline, David Skinner
We consider the Moyal deformation of self-dual gravity. In the conformal primary basis, holomorphic collinear limits of the amplitudes of this theory show that it enjoys a perturba…
The 4d/2d correspondence in twistor space and holomorphic Wilson lines
Wei Bu, Eduardo Casali
We give an explicit realization of the 4d local operator / 2d conformal block correspondence of Costello and Paquette in the case of gauge theories. This is accomplished by lifting…
