Radiative double copy for EinsteinYangMills theory
Abstract
Recently, a doublecopy formalism was used to calculate gravitational radiation from classical YangMills radiation solutions. This work shows that the YangMills theory coupled to a biadjoint scalar field admits a radiative double copy that agrees with solutions in the EinsteinYangMills theory at the lowest finite order. Within this context, the tracereversed metric h^{̄μ ν} is a natural double copy of the gauge boson A^{μ a} . This work provides additional evidence that solutions in gauge and gravity theories are related, even though their respective Lagrangians and nonlinear equations of motion appear to be different.
