Implications of spacetime quantization for the Bahcall–Waxman neutrino bound

摘要: There is growing interest in quantum-spacetime models which small departures from Lorentz symmetry are governed by the Planck scale. In particular, several studies have considered possibility that these violations of may affect various astrophysical observations, such as evaluation GZK limit for cosmic rays, interaction TeV photons with far infrared background and arrival time different energies cosmological sources. We show same Planck-scale led to a modification also significant implications Bahcall–Waxman bound on flux high-energy neutrinos produced photo–meson interactions.
