Description
The effects of isotropic, non-birefringent Lorentz violation in the photon sector can be studied with air showers induced by ultra-high-energy cosmic rays.
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 $\langle X_\text{max}\rangle$ and its shower-to-shower fluctuations $\sigma(X_\text{max})$.
In order to improve the search for the Lorentz violation, these modifications, which achieve Lorentz violation, have been implemented in the 3-dimensional air shower simulation program CORSIKA. This allows the inclusion of observables unavailable to a 1-dimensional simulation such as those connected to the lateral particle distribution.
Preliminary results from the 3-dimensional shower simulations will be presented.
