Soft gravitational radiation from ultra-relativistic collisions at sub- and sub-sub-leading order
Abstract Using soft-graviton theorems a well-known zero-frequency limit (ZFL) for the gravitational radiation flux dE GW /dω is re-derived and extended to order O ω $$ \mathcal{O}\left(\omega \right) $$ and O ω 2 $$ \mathcal{O}\left({\omega}^2\right) $$ for arbitrary massless multi-particle collisio...
