 Radiation Reaction from Soft Theorems / Di Vecchia, Paolo ; Heissenberg, Carlo ; Russo, Rodolfo ; Veneziano, Gabriele Radiation reaction (RR) terms at the third post-Minkowskian (3PM) order have recently been found to be instrumental in restoring smooth continuity between the non-relativistic, relativistic, and ultra-relativistic (including the massless) regimes.
