TL;DR
This paper explores how high-precision Drell-Yan measurements at the LHC can improve understanding of non-perturbative QCD effects by analyzing the forward-backward asymmetry to refine parton distribution functions.
Contribution
It introduces a PDF profiling method using the neutral-current Drell-Yan forward-backward asymmetry with xFitter to enhance PDF determination.
Findings
High-statistics DY data significantly constrain PDFs.
Forward-backward asymmetry provides sensitive probes of non-perturbative QCD.
Results improve the accuracy of parton distribution functions.
Abstract
We investigate the impact of high-statistics Drell-Yan (DY) measurements at the LHC on the study of non-perturbative QCD effects from parton distribution functions (PDF). We present the results of a PDF profiling analysis based on the neutral-current DY forward-backward asymmetry, using the open source fit platform xFitter.
