摘要

在有限温度波多尔斯基广义电动力学的框架内研究了电子-正电子湮灭过程。在这个理论中，一个高导数项修改了光子动力学扇区，在保持规范不变性的同时引入了一个大质量模式。热效应被纳入使用实时热场动力学形式。计算了总截面，分析了波多尔斯基参数和热效应对散射过程的影响。

Electron-positron scattering at finite temperature in Podolsky electrodynamics

The electron-positron annihilation process is investigated within the framework of Podolsky’s generalized electrodynamics at finite temperature. In this theory, a higher-derivative term modifies the photonic kinetic sector, introducing a massive mode while preserving gauge invariance. Thermal effects are incorporated using the real-time Thermo Field Dynamics formalism. The total cross section is calculated, and the individual contributions of the Podolsky parameter and thermal effects are analyzed to highlight their influence on the scattering process.
