Violation of Lorentz symmetries and thermal effects in Compton scattering

TL;DR

This paper investigates how Lorentz symmetry violations and thermal effects alter the differential cross section in Compton scattering, using extended QED and Thermofield Dynamics, revealing dominant corrections under specific conditions.

Contribution

It introduces a combined analysis of Lorentz symmetry violation and thermal effects on Compton scattering within an extended QED framework.

Findings

Differential cross section is affected by both Lorentz violation and thermal effects.

Corrections become dominant in certain parameter regimes.

Results are compared with existing literature for validation.

Abstract

In this paper, the differential cross section for the Compton scattering process is calculated. Two types of corrections are investigated: corrections due to violation of Lorentz symmetry and thermal effects. An extended QED is considered to introduce the parameter that leads to the breaking of symmetry. While temperature effects are introduced using Thermofield Dynamics formalism. It is shown that the differential cross section changes with both corrections. These corrections are dominant at appropriate limits. These special cases are analyzed and compared with other results from the literature.
