Implications of spacetime quantization for the Bahcall–Waxman neutrino bound
Implications of spacetime quantization for the Bahcall–Waxman neutrino bound
There is growing interest in quantum-spacetime models in which small departures from Lorentz symmetry are governed by the Planck scale. In particular, several studies have considered the possibility that these small violations of Lorentz symmetry may affect various astrophysical observations, such as the evaluation of the GZK limit for cosmic …
