S.V.Chekanov, L.Zawiejski
TL;DR
This paper investigates two-particle correlations in deep-inelastic scattering at HERA to test perturbative QCD predictions and quark fragmentation universality, comparing results with e+e- collision data and analyzing current-target region correlations.
Contribution
It provides the first detailed comparison of two-particle correlations in DIS at HERA with e+e- collision data, testing QCD and fragmentation universality.
Findings
Correlations at small angular separations are consistent with e+e- collision results.
Distinct correlation patterns are observed between current and target regions.
Results support the universality of quark fragmentation processes.
Abstract
Correlations in deep-inelastic scattering at HERA are investigated in order to test perturbative QCD and quark fragmentation universality. Two-particle correlations at small angular separations are measured in the Breit frame and compared to e+e- collisions. Also presented are the correlations between the current and target regions of the Breit frame.
