Iterating QCD scattering amplitudes in the high-energy limit

Vittorio Del Duca
2018 Journal of High Energy Physics  
We analyse the high-energy limit of the gluon-gluon scattering amplitude in QCD, and display an intriguing relation between the finite parts of the one-loop gluon impact factor and the finite parts of the two-loop Regge trajectory.
