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…
Factorization and resummation at next-to-leading-power
Leonardo Vernazza
We discuss recent progress concerning the resummation of large logarithms at next-to-leading power (NLP) in scattering processes such as Drell-Yan and deep inelastic scattering nea…
Region analysis of QED massive fermion form factor
Jaco ter Hoeve, Eric Laenen, Coenraad Marinissen +2
We perform an analysis of the one- and two-loop massive quark form factor in QED in a region expansion, up to next-to-leading power in the quark mass. This yields an extensive set…
Next-to-leading power resummed rapidity distributions near threshold for Drell-Yan and diphoton production
Robin van Bijleveld, Eric Laenen, Leonardo Vernazza +1
We consider Drell-Yan production and QCD-induced diphoton production and compute their rapidity distributions up to next-to-leading power (NLP) in the threshold variable. We give r…
Threshold factorization of the Drell-Yan quark-gluon channel and two-loop soft function at next-to-leading power
Alessandro Broggio, Sebastian Jaskiewicz, Leonardo Vernazza
We present a factorization theorem of the partonic Drell-Yan off-diagonal processes in the kinematic threshold regime at general…
