High Energy Resummation of Drell-Yan Processes

TL;DR

This paper develops a high-energy resummation framework for Drell-Yan processes in perturbative QCD, enabling more accurate predictions at very high energies beyond fixed order calculations.

Contribution

It introduces a method to perform all-order high-energy resummation for Drell-Yan cross-sections, extending beyond NNLO accuracy.

Findings

Resummed results match fixed order at NLO and NNLO.

Predictions provided at NNNLO and higher orders.

Framework applicable to future high-energy collider analyses.

Abstract

We present a computation of the inclusive Drell-Yan production cross-section in perturbative QCD to all orders in the limit of high partonic centre-of-mass energy. We compare our results to the fixed order NLO and NNLO results in MSbar scheme, and provide predictions at NNNLO and beyond. Our expressions may be used to obtain fully resummed results for the inclusive cross-section.
