Long-Range Interactions in Celestial CFT
Sangmin Choi, Ameya Kadhe, Andrea Puhm
Loop corrections in QED and gravity have recently been conjectured to give rise to an infinite tower of logarithmic soft theorems governing the universal low-energy behavior of pho…

Exact Infrared Triangle in Massless sQED with Long-range Interactions
Sangmin Choi, Ameya Kadhe, Andrea Puhm
The logarithmic soft photon theorem in four spacetime dimensions encodes an infinite-dimensional asymptotic symmetry which acts on massive matter as a divergent superphaserotation.…
