摘要: We present a calculation of the production neutrinos during propagation ultra-high energy cosmic rays from their astrophysical sources to us. Photoproduction interactions are modeled with event generator SOPHIA that represents very well experimentally measured particle cross sections at accelerator energies. give fluxes expected different assumptions on ray source distributions, injection spectra, cosmological evolution and cosmologies, compare them Waxman-Bahcall limit neutrinos. estimate rates for detection neutrino induced showers in km3 water detector. The ratio local high flux is crucial parameter distinguishing between (top-down) scenarios origin.
