Query: Classical double copy from Color Kinematics duality: A proof in the soft
  limit   Classical double copy is an intriguing relationship between classical
solutions to a gravity theory and solutions to classical Yang-Mills equations.
Although formally inspired by the double copy relation between (quantum)
scattering amplitudes in QCD and perturbative gravity, a direct proof of the
former from the latter continues to be under investigation. In this paper, we
attempt to prove classical double copy from the color-kinematics duality
symmetry of QCD amplitudes in a restricted setting. That is we consider
radiative solutions with classical scattering sources in Yang-Mills theory and
perturbative gravity in D > 4 spacetime dimensions. We show that when the
frequency of radiation is much smaller than the characteristic frequency of the
process, then at the subleading order in frequency, the classical double copy
relating radiative gluon field to radiative gravitational field can be proved
from the color-kinematics duality of QCD amplitudes.
