Lorentz Invariance Violation and Chemical Composition of Ultra High Energy Cosmic Rays — •Andrey Saveliev1, Luca Maccione2,3, and Günter Sigl11Universität Hamburg, II. Institut für Theoretische Physik, Hamburg, Germany — 2Ludwig-Maximilians-Universität, Fakultät für Physik, München, Germany — 3Max-Planck-Institut für Physik, Werner-Heisenberg-Institut, München, Germany

After a general introduction to Lorentz Invariance Violation (LIV) we present constraints on Planck scale suppressed Lorentz breaking terms coming from the comparison between theoretical predictions and current observations of ultra high energy cosmic rays (UHECR). Finally, we will discuss further prospects and future developments in the topic, focusing in particular on the possible impact on the chemical composistion of UHECRs.
