Abstract

In this paper, we investigate the production process of a photon pair in a regime of quantum electrodynamics, considering the presence of a constant four-vector that defines a privileged direction in spacetime, resulting in Lorentz symmetry violation. We explore Lorentz violation in the context of vectorial nonminimal coupling, where we analyze the modifications introduced by this coupling in the scattering amplitude at the vertex. Moreover, we delve into Lorentz violation with axial-like nonminimal coupling. Both analyses are conducted by examining the constant four-vector of both time-like and space-like types.

γ对生产中的洛伦兹违反（e + e - → γ γ)

在本文中，我们研究了量子电动力学体系中光子对的产生过程，考虑到存在一个恒定的四矢量，它定义了时空中的一个特权方向，导致洛伦兹对称性违反。我们探讨了矢量非最小耦合背景下的洛伦兹违反，分析了这种耦合对顶点散射振幅的修正。此外，我们还深入研究了轴类非最小耦合的洛伦兹违反。这两项分析都是通过研究类时间和类空间类型的恒定四矢量进行的。
