WebJan 10, 2024 · In this letter, we examine the Breit-Wheeler process as a function of impact parameter in heavy-ion collisions based on the external classical field approach [9] and go through the generalized EPA (gEPA1) assumption toward a formula, which shows strong impact-parameter dependence of the cross section and spectra. WebThe advent of laser-driven high-intensity $\\gamma$-photon beams has opened up new opportunities for designing advanced photon-photon colliders. Such colliders have the potential to produce a large yield of linear Breit-Wheeler (LBW) pairs in a single shot, which offers a unique platform for studying the polarized LBW process. In our recent work …
