SPACE-TIME RESOLVED BREIT-WHEELER PROCESS FOR A MODEL SYSTEM
We study the creation process of an electron-positron pair as a result of the collision between two incoming photons with full spatial and temporal resolution. The dynamics of the four involved particles is described by a simplified model based on a Yukawa Hamiltonian in one spatial dimension. Consistent with lowest order perturbation theory, since only sets of four intermediate off-resonant states facilitate the coupling between the initial and final scattering states, we can adiabatically eliminate them leading to an analytical solution.
