摘要:

采用实时Dirac-Heisenberg-Wigner方法,通过提出有效能量的概念,数值研究了任意极化电场中非微扰性质的多光子对产生中的质量移动效应.结果表明,理论计算结果与数值计算结果吻合得很好。首次考虑了产生粒子的动量和外场的极化在质量移动效应中的作用。这些结果可以加深对非微扰阈值区电子对产生的理解。此外,在即将进行的实验中可以观察到明显的质量漂移效应,并且可以用作探针来区分电子-正电子对产生与其他背景事件。

英文摘要:

The mass shift effects in multiphoton pair production of a nonperturbative nature for arbitrary polarized electric fields are investigated numerically by employing the real-time Dirac-Heisenberg-Wigner formalism, and theoretically by proposing an effective energy concept. It is found that the theoretical results are agreement with the numerical ones very well. It is the first time to consider the roles of the momenta of created particles and the polarizations of external fields played in the mass shift effects. These results can deepen the understanding of pair production in the nonperturbative threshold regime. Moreover, the distinct mass shift effects are observable in the forthcoming experiments and can be used as a probe to distinguish the electron-positron pair production from other background events.
