Gluon radiation from a classical point particle: Recoil effects: https://arxiv.org/abs/2109.01736
Isobel Kolbe, Mawande Lushozi
We propose a formula for gluon radiation in the fragmentation region. By comparing tree-level bremsstrahlung of a spin-less quark to the known result for gluon radiation from a classical particle struck by a sheet of colored glass arXiv:1903.01381, arXiv:1911.12738 we modify the classical formula to take into account the recoil of the struck particle. The new formula produces the correct perturbative behaviour at high momentum of the radiated gluon.
