Contribution
It introduces an analysis of the differential cross section's impact on pair beaming, bridging laboratory and astrophysical applications.
Findings
Differential cross section significantly affects pair angular distribution.
Energy distribution of pairs is sensitive to the cross section details.
Results are relevant for optimizing laser-induced gamma-ray experiments.
Abstract
The pair beaming in the Breit-Wheeler (BW) process is investigated. We examine the effect of the BW differential cross section on pair angular and energy distributions. Although, this study is relevant for laser induced intense gamma-ray source collisions experiments, we apply the pair beaming in astrophysical context, in particular for Active Galactic Nuclei (AGN).
