UHECR propagation in the Galaxy: clustering versus isotropy
Jaime Alvarez-Muñiz, Ralph Engel, Todor Stanev
Recently the AGASA Collaboration presented data suggesting a significant clustering of ultra-high energy cosmic rays coming from the outer Galaxy region. In this paper we calculate…
Soft interactions (presented at ISMD31)
Ralph Engel
A brief introduction to the theory and phenomenology of soft interactions is given, focusing on total and elastic cross sections and multiparticle production.
Propagation of ultra-high energy protons in regular extragalactic magnetic fields
Todor Stanev, David Seckel, Ralph Engel
We study the proton flux expected from sources of ultra high energy cosmic rays (UHECR) in the presence of regular extragalactic magnetic fields. It is assumed that a local source…
Neutrinos from propagation of ultra-high energy protons
Ralph Engel, David Seckel, Todor Stanev
We present a calculation of the production of neutrinos during propagation of ultra-high energy cosmic rays from their astrophysical sources to us. Photoproduction interactions are…
