Soft gravitational radiation from ultra-relativistic collisions at sub- and sub-sub-leading order
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 $ \mathcal{O}\left(\omega \right) $ and $ \mathcal{O}\left({\omega}^2\right) $ for arbitrary massless multi-particle collisions. The (angle-integ...
