Matthew Wing (on behalf of the ZEUS Collaboration)
TL;DR
This paper performs a next-to-leading-order QCD analysis of ZEUS diffractive data to extract parton distribution functions, using dijet production data to constrain the gluon density, and successfully predicts dijet photoproduction measurements.
Contribution
It introduces a comprehensive NLO QCD analysis of ZEUS diffractive data incorporating dijet production to refine the gluon density in diffractive PDFs.
Findings
Extracted diffractive parton distribution functions consistent with data.
Gluon density constrained by diffractive dijet production.
Predictions accurately describe dijet photoproduction measurements.
Abstract
ZEUS inclusive diffractive cross-section measurements have been used in a next-to-leading-order QCD analysis to extract the diffractive parton distribution functions. Data on diffractive dijet production in deep inelastic scattering have also been used to constrain the gluon density. Predictions based on the extracted parton densities are able to describe measurements of dijet photoproduction.
