Exponentiation of soft quark effects from the replica trick
Melissa van Beekveld, Leonardo Vernazza, Chris D. White
In this paper, we show that multiple maximally soft (anti-)quark and gluon emissions exponentiate at the level of either the amplitude or cross-section. We first show that such emi…
Universality of next-to-leading power threshold effects for colourless final states in hadronic collisions
V. Del Duca, E. Laenen, L. Magnea +2
We consider the production of an arbitrary number of colour-singlet particles near partonic threshold, and show that next-to-leading order cross sections for this class of processe…
Infrared singularities in the high-energy limit
Lorenzo Magnea, Vittorio Del Duca, Claude Duhr +2
We use our current understanding of the all-order singularity structure of gauge theory amplitudes to probe their high-energy limit. Our starting point is the dipole formula, a com…
Path integral approach to eikonal and next-to-eikonal exponentiation
E. Laenen, G. Stavenga, C. D. White
We approach the issue of exponentiation of soft gauge boson corrections to scattering amplitudes from a path integral point of view. We show that if one represents the amplitude as…
