Abstract:
In the presence of an electromagnetic background plane-wave field, electron, positron, and photon states are not stable, because electrons and positrons emit photons and photons decay into electron- positron pairs. This decay of the particle states leads to an exponential damping term in the probabilities of single nonlinear Compton scattering and nonlinear Breit-Wheeler pair production. We investigate, analytically and numerically, the total and spin- and polarization- resolved differential probabilities of these nonlinear QED processes, taking the particle states' decay into account.
