Trident pair production in a constant crossed field    [PDF]

B. King, H. Ruhl

For the trident process in a constant crossed field, we isolate the one-step mechanism involving a virtual intermediate photon from the two-step mechanism involving a real photon. The one-step process is found to be measurable combining currently-available electron beams with few-cycle laser pulses. The two-step process differs appreciably in magnitude and dynamics from integrating the product of sub-steps over photon lightfront momentum, challenging numerical simulation efforts.
