    "abstract": "Although Lorentz symmetry has been tested at low energy with extremely good\naccuracy, its validity at very high energy is much less well established. If\nLorentz symmetry violation (LSV) is energy-dependent (e.g. $\\propto E^2$), it\ncan be of order 1 at Planck scale and undetectable at GeV scale or below.\nSimilarly, superluminal particles with positive mass and energy (superbradyons)\ncan exist and be the ultimate building blocks of matter. We discuss a few\ncosmological consequences of such a scenario, as well as possible experimental\ntests.",
