Effect of differential cross section in Breit–Wheeler pair production

X Ribeyre, E dHumières, S Jequier, V T Tikhonchuk2018年Plasma Physics and Controlled FusionIF 2.2出版社

The possibility of achieving a pair beaming in the Breit–Wheeler (BW) electron/positron pair creation process is investigated in this paper. We examine the effect of the BW differential cross section on the pair's angular and energy distributions. Although this study is relevant for laser induced intense gamma-ray source collision experiments, we apply this pair beaming effect in an astrophysical context, in particular for active galactic nuclei (AGN).
