Disentangling the Regge cut and Regge pole in perturbative QCD
The high-energy limit of gauge-theory amplitudes features both a Regge pole and Regge cuts. We show how to disentangle these, and hence how to determine the Regge trajectory beyond two loops. While the nonplanar part of multiple Reggeon <math display="inline"><mi>t</mi>&l...
