Abstract. Special relativity has been tested at low energy with great accuracy,
but these results cannot be extrapolated to the very highenergy region.
Introducing a critical distance scale, $a$ , below $10^{25}~ cm$ (the
wavelength scale of the highestenergy observed cosmic rays) allows to
consider models, compatible with standard tests of special relativity,
where a small violation of Lorentz symmetry ($a$ can, for instance, be the
Planck length $\approx 10^{33}~cm$) produces dramatic effects on the
properties of very highenergy particles. Lorentz symmetry violation may
potentially solve all the basic problems raised by the highestenergy cosmic
rays (origin and energy, propagation...). Furthermore, superluminal sectors of
matter may exist and release very highenergy ordinary particles or directly
produce very highenergy cosmicray events with unambiguous signatures
in very large detectors. We discuss these phenomena, as well as the
cosmicray energy range (well below the energy scale associated to the
fundamental length) and experiments where they could be detected and studied.
