One-loop Single Real Emission Contributions to Inclusive Higgs   Production at NNNLO
  I discuss the contributions of the one-loop single-real-emission amplitudes, $gg\to H g$, $qg\to H q$, etc. to inclusive Higgs boson production through next-to-next-to-next-to-leading order in the strong coupling.
