Obtaining bounds from ultra-high energy cosmic rays in isotropic modified Maxwell theory

Abstract

This article reviews the methods used to obtain a two-sided bound on isotropic modified Maxwell theory from experimental data of ultra high-energy cosmic rays in 2008. The bound is updated with results from the HEGRA experiment.
