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…
Towards all-order factorization of QED amplitudes at next-to-leading power
E. Laenen, J. Sinninghe Damsté, L. Vernazza +2
We generalise the factorization of abelian gauge theory amplitudes to next-to-leading power (NLP) in a soft scale expansion, following a recent generalisation for Yukawa theory. Fr…
Diagrammatic resummation of leading-logarithmic threshold effects at next-to-leading power
N. Bahjat-Abbas, D. Bonocore, J. Sinninghe Damsté +4
Perturbative cross-sections in QCD are beset by logarithms of kinematic invariants, whose arguments vanish when heavy particles are produced near threshold. Contributions of this t…
On next-to-leading power threshold corrections in Drell-Yan production at NLO
Nadia Bahjat-Abbas, J. Sinninghe Damsté, Leonardo Vernazza +1
The cross-section for Drell-Yan production of a vector boson has been previously calculated at next-to-next-to-leading order, supplemented by enhanced logarithmic terms associated…
