Abstract
Lorentz symmetry has been tested at low energy with great accuracy, but its extrapolation to very high-energy phenomena is much less well established. We expect a possible breaking of Lorentz symmetry to be a very high energy and very short distance phenomenon, compatible with existing data. If textbook special relativity is only an approximate property of the equations describing a sector of matter above some critical distance scale, superluminal sectors of matter may exist related to new degrees of freedom not yet discovered experimentally. The new superluminal particles ("superbradyons") would have positive mass and energy, and behave kinematically like "ordinary" particles (those with critical speed in vacuum equal to c , the speed of light) apart from the difference in critical speed (we expect c_i >> c , where c_i is the critical speed of a superluminal sector of matter). At speed v > c , they are expected to release "Cherenkov" radiation ("ordinary" particles) in vacuum. If superluminal particles exist, they could provide most of the cosmic (dark) matter and produce very high-energy cosmic rays compatible with unexplained discoveries reported in the literature. We discuss: a) the possible relevance of superluminal matter to the composition, sources and spectra of high-energy cosmic rays; b) signatures and experiments allowing to possibly explore such effects.
