From AdS correlators to Carrollian amplitudes with the scattering equation
Tim Adamo, Iustin Surubaru, Bin Zhu
The scattering equations relate massless scattering kinematics to marked points on a Riemann sphere, and underpin remarkable formulae for the full tree-level S-matrices of many int…

Carrollian Amplitudes and Holographic Correlators in AdS3/CFT2
Iustin Surubaru, Bin Zhu
We study Carrollian amplitudes of massless scalars in (1+2) Minkowski space. Using the prescription recently shown by Alday et al. [JHEP 03 (2025) 158] originally designed for the…

Conformal blocks from celestial graviton amplitudes
Iustin Surubaru, Bin Zhu
Four-point gluon and graviton correlators in celestial holography are famously non-analytic, having distributional support. In this work, we propose an alternative graviton correla…
