Limits on Non-Linear Electrodynamics

TL;DR

This paper develops a framework to use existing experiments testing QED to also constrain non-linear electrodynamics, establishing limits on its parameters and discussing implications for charged particles.

Contribution

It introduces a generalized framework for testing non-linear electrodynamics using experiments designed for QED, setting new bounds on NLED parameters.

Findings

Established limits on NLED parameters from experimental data

Generalized QED predictions within NLED framework

Discussed implications for bound systems and charged particles

Abstract

In this paper we set a framework in which experiments whose goal is to test QED predictions can be used in a more general way to test non-linear electrodynamics (NLED) which contains low-energy QED as a special case. We review some of these experiments and we establish limits on the different free parameters by generalizing QED predictions in the framework of NLED. We finally discuss the implications of these limits on bound systems and isolated charged particles for which QED has been widely and successfully tested.
