Lorentz violation as a quantum-gravity signature
arXiv:astro-ph/0508625 · doi:10.1142/S0217751X05024201
Abstract
Many theoretical approaches to quantum gravity predict the breakdown of Lorentz symmetry at Planck energies. Kinematical cosmic-ray studies are a sensitive tool in the search for such effects. This talk discusses the construction of test dispersion relations for such analyses.
