论文摘要
我们评估了不均匀的静态空事步骤的电势势能在电场中出现同质性的假想部分有效的Euler-Heisenberg-Schinginger动作，该动作由带电粒子的真空波动带有具有磁性强度的带电粒子的真空波动。结果是收敛的，对于$ g $的所有速度磁比$ g $的值，$ g = 2 $。我们考虑与QEDβ功能的关系，该功能也被认为是$ g $的周期性。我们使用这种新颖的方法证实存在渐近自由条件，并记录了存在渐近自由的$ g $值范围。
We evaluate for the inhomogeneous static electric Sauter step potential the imaginary part of the emerging homogeneous in electric field effective Euler-Heisenberg-Schwinger action sourced by vacuum fluctuations of a charged particle with magnetic moment of arbitrary strength. The result is convergent for all values of gyromagnetic ratio $g$, periodic in $g$, with a cusp at $g=2$. We consider the relation to the QED beta-function which is also found to be periodic in $g$. We confirm presence of asymptotic freedom conditions using this novel method and document a wider range of $g$-values for which asymptotic freedom is present.
