%0 Journal Article %T Kinematical Lorentz-symmetry tests at particle colliders %A Ralf Lehnert %J Physics %D 2014 %I arXiv %X Violations of Lorentz symmetry are typically associated with modifications of one-particle dispersion relations. The physical effects of such modifications in particle collisions often grow with energy, so that ultrahigh-energy cosmic rays provide an excellent laboratory for measuring such effects. In this talk we argue that collisions at particle colliders, which involve much smaller energies, can nevertheless yield competitive constraints on Lorentz breaking. %U http://arxiv.org/abs/1403.6051v1
