Studying effects of Lorentz violation in the photon sector using extensive air shower simulations — •Nico Spornhauer, Fabian Duenkel, Marcus Niechciol, and Markus Risse — Center for Particle Physics Siegen, Experimentelle Astroteilchenphysik, Universität Siegen
Ultra-high-energy cosmic rays induce extensive air showers involving secondary particles, which can exceed the energies reached by today’s accelerators. The effects of isotropic, non-birefringent Lorentz violation in the photon sector can be studied at these high energies. Using the 1-dimensional air shower simulation program CONEX, bounds on the studied Lorentz violation were set based on the significant reduction of the average atmospheric depth of the shower maximum ⟨ Xmax⟩ and its shower-to-shower fluctuations σ(Xmax). We implemented modifications achieving Lorentz violation into the 3-dimensional air shower simulation program CORSIKA. The aim is an improved search for Lorentz violation by including observables unavailable to a 1-dimensional simulation such as those connected to the lateral particle distribution. We present preliminary results for the 3-dimensional shower simulations.
