Study of Deep Inelastic ep-Scattering at High-Q^2 with ZEUS at HERA

TL;DR

This paper reports measurements of deep inelastic ep scattering cross sections at high Q^2 using ZEUS data, confirming the standard model predictions and extracting the structure function xF_3 from combined e^-p and e^+p data.

Contribution

It provides new high-Q^2 cross section measurements and extracts the structure function xF_3 by combining different data sets, testing the standard model's accuracy.

Findings

Measured cross sections agree with standard model predictions.

Extracted xF_3 structure function aligns with theoretical expectations.

Data covers 1994-97 e^+p and 1998-99 e^-p running periods.

Abstract

Measurements of differential cross sections for deep inelastic ep neutral-current (NC) and charged-current (CC) reactions are presented using data taken during the 1994-97 e^+p and the 1998-99 e^-p running periods. The structure function xF_3 has been extracted combining NC e^-p and e^+p data sets. Both the measured cross sections and xF_3 are well described by the standard model predictions using standard PDF's.
