Fragmentation in DIS

TL;DR

This paper investigates fragmentation in deep-inelastic scattering at HERA to test perturbative QCD and quark fragmentation universality, comparing results with electron-positron collisions and exploring the target region.

Contribution

It provides new experimental results on fragmentation properties in DIS, including single particle distributions and two-particle correlations, extending studies to the target region of the Breit frame.

Findings

Fragmentation properties in DIS are consistent with QCD predictions.

Quark fragmentation universality is supported by comparison with $e^{+}e^{-}$ data.

New insights into the target region fragmentation are presented.

Abstract

The fragmentation properties in deep-inelastic scattering (DIS) at HERA are investigated in order to test perturbative QCD and quark fragmentation universality. Selected results for the inclusive single particle distributions and the angular two-particle correlations in the current region of the Breit frame are presented and compared to results from $e^{+}e^{-}$ collisions. The extension of the DIS fragmentation studies to the target region of the Breit frame are also reported.
