Gravitational Radiation from the Double Copy

Abstract: We show that the perturbative radiative solutions to the classical Yang-Mills equations from the scattering of spinning particle sources exhibit color-kinematic duality, a duality originally discovered in the context of perturbative tree-level scattering amplitudes of Yang-Mills theory. This enables a classical double-copy construction that generates corresponding classical solutions in string gravity (axion-dilaton gravity). While the original double copy of scattering amplitudes traces back to results in perturbative string theories, we find that classical open and closed strings are possible “UV completions” to these worldline effective field theories of the sources by comparing to the low energy radiation from these rotating strings. Moreover, we show that the higher dimensional operators encoding tidal deformation can also be added to this construction, provided that the Wilson coefficients of the dilatonic and axionic operators are fixed with respect to the gravitational ones.
