强laser脉冲中三叉戟对的产生

Trident pair production in strong laser pulses

Anton Ilderton

摘要:

计算了强激光背景下三叉戟对产生的振幅。我们允许有限的脉冲宽度,同时仍然处理强场QED中的激光场非微扰。我们的方法明确地揭示了一步和两步过程的个人贡献。我们还揭示了规范不变性在振幅中所起的作用,并讨论了我们的结果与光学定理之间的关系。

英文摘要:

We calculate the trident pair production amplitude in a strong laser background. We allow for finite pulse duration, 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.
