Query: Infrared singularities of QCD scattering amplitudes in the Regge limit
  to all orders   Scattering amplitudes of partons in QCD contain infrared divergences which
can be resummed to all orders in terms of an anomalous dimension.
Independently, in the limit of high-energy forward scattering, large logarithms
of the energy can be resummed using Balitsky-Fadin-Kuraev-Lipatov theory. We
use the latter to analyze the infrared-singular part of amplitudes to all
orders in perturbation theory and to next-to-leading-logarithm accuracy in the
high-energy limit, resumming the two-Reggeon contribution. Remarkably, we find
a closed form for the infrared-singular part, predicting the Regge limit of the
soft anomalous dimension to any loop order.
