Trident pair-production in strong-field QED: pulse shape dependence — •Uwe Hernandez Acosta and Burkhard Kämpfer — Institute of Radiation Physics, Helmholtz-Zentrum Dresden-Rossendorf

We present calculations of trident pair (e+,e-) production in laser-electron collisions within the framework of strong-field QED. The Furry picture is suitable to study the impact of the beam shape. Analog to Compton and Breit-Wheeler processes, rich structure patterns can emerge in various observables reflecting pulse features. The trident process is interesting as first step in seeded cascades as well-controlled QED background.
