TL;DR
This paper investigates potential factorisation breaking in diffractive dijet photoproduction at HERA, analyzing experimental data to understand discrepancies between H1 and ZEUS results, focusing on hadronisation and phase space effects.
Contribution
It provides a detailed analysis of factorisation breaking effects in diffractive dijet photoproduction, highlighting the impact of hadronisation corrections and phase space differences on experimental results.
Findings
Differences in hadronisation corrections influence results.
Phase space variations contribute to discrepancies.
Analysis suggests factorisation breaking effects are significant.
Abstract
Recent experimental data on dijet cross sections in diffractive photoproduction at HERA collider are analysed with an emphasis on QCD factorisation breaking effects. The possible sources of the contradiction in conclusions of H1 and ZEUS collaborations such as different hadronisation corrections and different phase space of both analyses are studied.
