Propagation of UHECRs

Astrophysics 2007-05-23 v2

Abstract

In this general introduction to Ultra High Energy Cosmic Rays (UHECRs) we discuss the propagation of UHE protons and the GZK feature that is expected approaching 1020\eV10^{20}\eV for homogeneously distributed sources. We also briefly present the effects of the propagation on other particles that can play the role of UHECRs. With the help of numerical simulations for the propgation of UHECRs, we show that the GZK feature cannot be accurately determined with the small sample of events with energies 1020\eV\sim10^{20}\eV detected thus far by the largest two experiments, AGASA and HiRes.
