Scattering in Black Hole Backgrounds and Higher-Spin Amplitudes: Part II
Yilber Fabian Bautista, Alfredo Guevara, Chris Kavanagh +1
We continue to investigate correspondences between, on the one hand, scattering amplitudes for massive higher-spin particles and gravitons in appropriate quantum-to-classical limit…
Towards Gravity From a Color Symmetry
Alfredo Guevara
Using tools from color-kinematics duality we propose a holographic construction of gravitational amplitudes, based on a 2d Kac-Moody theory on the celestial sphere. In the $N\to \i…
Notes on Resonances and Unitarity from Celestial Amplitudes
Diego García-Sepúlveda, Alfredo Guevara, Justin Kulp +1
We study the celestial description of the sigma model in the large limit as introduced by Coleman, Jackiw and Politzer. Focusing on three dimensions, we analyze the impl…
