Detection of cosmogenic neutrinos with the KM3NeT telescope

Cosmogenic neutrinos are produced during the propagation of ultra high energy cosmic rays (UHECR) through the cosmological microwave background radiation. The extragalactic origin of UHECR guarantees generation of high energy cosmogenic neutrinos, however, the flux depends on the currently unknown properties of UHECR, for example, the chemical composition and distribution of the sources and their evolution with redshift. Estimations of cosmogenic neutrino fluxes, which are constrained by UHECR observations, include a range of models in which a detectable signal could be produced in a very large volume high-energy neutrino telescope. In particular the favorable scenarios are based on the models with a pure proton composition. The possible event rate of cosmogenic neutrinos in the KM3NeT telescope for the different flux models is discussed in this paper.
