Disentangling the Regge cut and Regge pole in perturbative QCD
Giulio Falcioni, Einan Gardi, Niamh Maher +2
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-parton scattering in the high-energy limit: climbing two- and three-Reggeon ladders
Leonardo Vernazza, Giulio Falcioni, Einan Gardi +2
We review recent progress on the calculation of scattering amplitudes in the high-energy limit. We start by illustrating the shockwave formalism, which allows one to calculate ampl…
Scattering amplitudes in the Regge limit and the soft anomalous dimension through four loops
Giulio Falcioni, Einan Gardi, Niamh Maher +2
Using rapidity evolution equations we study two-to-two gauge-theory scattering amplitudes in the Regge limit. We carry out explicit computations at next-to-next-to-leading logarith…
The Soft Anomalous Dimension at four loops in the Regge Limit
Niamh Maher, Giulio Falcioni, Einan Gardi +2
The soft anomalous dimension governs the infrared divergences of scattering amplitudes in general kinematics to all orders in perturbation theory. By comparing the recent Regge-lim…
Threshold resummation of new partonic channels at next-to-leading power
Melissa van Beekveld, Leonardo Vernazza, Chris D. White
Collider observables involving heavy particles are subject to large logarithmic terms near threshold, which must be summed to all orders in perturbation theory to obtain sensible r…
Next-to-leading power two-loop soft functions for the Drell-Yan process at threshold
Alessandro Broggio, Sebastian Jaskiewicz, Leonardo Vernazza
We calculate the generalized soft functions at at next-to-leading power accuracy for the Drell-Yan process at threshold. The operator definitions of these obje…
Next-to-leading power threshold corrections for finite order and resummed colour-singlet cross sections
Melissa van Beekveld, Eric Laenen, Jort Sinninghe Damsté +1
We study next-to-leading-power (NLP) threshold corrections in colour-singlet production processes, with particular emphasis on Drell-Yan (DY) and single-Higgs production. We assess…
