Abstract

We propose to investigate the potentialities of CTA to detect a Lorentz invariance violation signal. This project is focused on the astrophysical modelling of the signal and the background with the aim to search for the best sources candidates and the best analyisis methods. Before CTA is taking data, we are going to work on common analysis of the current experiments (Fermi, \hess, MAGIC, VERITAS, AMS-02 etc.). The idea is to improve the limits by combined analysis and at the same time start to develop new methods to be used with CTA data when available. (AU)
