Trident Pair Production in Strong Laser Pulses

  • 1. Department of Physics, Umeaa University, SE-901 87 Umeaa (Sweden)

Description

We calculate the trident pair production amplitude in a strong laser background. We allow for finite pulse durations, while still treating the laser fields nonperturbatively in strong-field QED. Our approach reveals explicitly the individual contributions of the one-step and two-step processes. We also expose the role gauge invariance plays in the amplitudes and discuss the relation between our results and the optical theorem.
