论文摘要
在这项工作中，我们考虑了Podolsky在海森伯格图片中通过Kallen方法论提出的广泛量子电动力学。我们研究了高阶导数对真空极化的定性和定量方面的影响。另外，还获得了通过扰动方案“ A la” Kallen自然出现的诱导电流和极化张量的最通用结构。之后，我们从单一和稳定的Podolsky理论的角度讨论了电荷重新归一化的物理含义。
In this work, we consider the generalized quantum electrodynamics proposed by Podolsky in Heisenberg picture via Kallen methodology. We investigate the effects of higher-order derivatives to understand the qualitative and quantitative aspects of vacuum polarization. In addition, the most general structure of induced current and polarization tensor that emerge naturally by a perturbative scheme "a la" Kallen is also obtained. Afterward, we discuss the physical implication of charge renormalization in the perspective of unitary and stable Podolsky theory.
