Beschreibung

Motivated by corresponding experimental prospects (such as E3 or LUXE at DESY) we study strong-field Breit-Wheeler pair production by bremsstrahlung gamma-rays propagating through a high-intensity optical laser wave. The influence of the broad frequency spectrum of the bremsstrahlung on the properties of the process in the transition region between the perturbative and the non-perturbative interaction regimes is analysed by calculating the total yield of pair production and the energy and angular distributions of the produced particles for a range of laser intensities [1]. A continuous shift of the major contributing interval of the bremsstrahlung frequencies during the transition is shown and characteristic signatures of the laser-dressed particle mass are highlighted.
