Abstract

We investigated the impact parameter dependence of the background field's effect on the coupling constant of the γγ→ l⁺ l^- γ process in heavy-ion collisions. The peripheral electric fields of heavy ions collide, and after photon annihilation into lepton pairs, the subsequent emission of radiation photons will be affected by the background field. Numerical estimates indicate that the dependence of this effect on the impact parameter is significant during this process.
