Dijet Cross Sections and Rapidity Gaps between Jets in photoproduction at HERA

TL;DR

This paper compares dijet cross sections and rapidity gap fractions in photoproduction at HERA with NLO calculations and Monte Carlo predictions, providing insights into QCD processes.

Contribution

It presents new 1995 data on dijet cross sections and rapidity gaps, comparing them to theoretical models and previous analyses.

Findings

Agreement between 1994 data and NLO calculations

New 1995 data aligns with Monte Carlo predictions

Rapidity gap fractions are quantified for the first time in this dataset

Abstract

Dijet cross sections from the original 1994 ZEUS data analysis are shown compared to NLO calculations. New 1995 cross sections are shown compared to Monte Carlo predictions. The fraction of dijet events with a rapidity gap inbetween the jets is also presented for the new 1995 data.
