Query: Three-loop soft function for energetic electroweak boson production at
  hadron colliders   We calculate the three-loop soft function for the production of an
electroweak boson (Higgs, $\gamma$, $W^\pm$, $Z$) with large transverse
momentum at a hadron collider. It is the first time a soft function for a
three-parton process is computed at next-to-next-to-next-to-leading order
(N$^3$LO). As a technical novelty, we perform the calculation in terms of
forward-scattering-type loop diagrams rather than evaluating phase space
integrals. Our three-loop result contains color-tripole contributions and
explicitly confirms predictions on the universal infrared structure of QCD
scattering amplitudes with three massless parton legs. The soft function is a
central ingredient in the factorized cross section for electroweak boson
production near the kinematic endpoint (threshold), where the invariant mass of
the recoiling hadronic radiation is small compared to its transverse momentum.
Our result is required for predictions of the near-threshold cross sections at
N$^3$LO and for the resummation of threshold logarithms at primed
next-to-next-to-next-to-leading logarithmic (N$^3$LL$^\prime$) accuracy.
