SimProp v2r2: a Monte Carlo simulation to compute cosmogenic neutrino fluxes

Abstract

We present an updated version of the SimProp Monte Carlo code: a simulation scheme to study the propagation of ultra-high-energy cosmic rays through diffuse extragalactic background radiation. The new version of the code presents two important updates: (i) it treats in a full stochastic approach all interaction channels involving ultra-high-energy cosmic rays and (ii) it takes into account the production of secondary (cosmogenic) neutrinos. This new version of SimProp was tested against different simulations code, in particular the production of secondary neutrinos was compared with the fluxes expected in the scenario of Engel, Seckel and Stanev.
