TL;DR
This paper investigates how polarized photon-induced large transverse momentum hadron pairs can be used to probe the polarized gluon distribution inside protons, incorporating resolved photon effects and scale variations.
Contribution
It provides theoretical predictions for polarized hadron pair production, including resolved photon contributions and energy scale effects, and compares them with recent experimental data.
Findings
Predictions match experimental results at 7.18 GeV.
Resolved photon contributions significantly affect the cross sections.
Proper combination of cross sections enhances the probe's effectiveness.
Abstract
Production of large-p_T hadron pairs by polarized photon on a longitudinally polarized proton towards probing the polarized gluon distribution is studied. Resolved photon contributions and the effect of changing the scales are taken into account, and predictions are presented. A very recent experimental result at c.m. energy 7.18 GeV is compared to our predictions extented down to this energy. A proper combination of cross sections is also considered.
