Inclusive Dijet Cross Sections in Neutral Current Deep Inelastic Scattering and Photoproduction at HERA

TL;DR

This paper reports measurements of inclusive dijet cross sections in neutral current deep inelastic scattering and photoproduction at HERA, comparing results with next-to-leading order perturbative QCD calculations to test theoretical predictions.

Contribution

It provides new experimental data on dijet production across a wide range of Q^2, enhancing the understanding of QCD in ep collisions.

Findings

Measured dijet cross sections in DIS and photoproduction.

Data agree with NLO perturbative QCD predictions within uncertainties.

Extends previous measurements to higher Q^2 ranges.

Abstract

Recent results from the \emph{ep} collier HERA are presented. Inclusive dijet cross sections have been measured in neutral current deep inelastic scattering, for virtualities of the exchanged boson in the range $125 < Q^{2} < 20\,000\; GeV^{2}$ and in photoproduction, $Q^{2} \sim 0 GeV^{2}$. The measurements are compared to perturbative QCD calculations at next-to-leading order.
