In a recent paper, Waxman and Bahcall (PRD 59, 023002) claimed that the present data on ultra-high energy cosmic rays imply a model-independent upper bound on extragalactic neutrino fluxes of 2*10^-8 GeV cm^-2 s^-1 ster^-1, independent of neutrino energy. Mannheim, Protheroe and Rachen (astro-ph/9812398) have repeated this calculation and confirmed the WB-bound, within a factor of 2, only at a very limited energy range of E_\nu \sim 10^(16-18) eV, while at other energies the neutrino flux is…

The IceCube collaboration has recently reported the observation of two events with energies in excess of 1 PeV. While an atmospheric origin of these events cannot be ruled out at this time, this pair
High energy neutrino detection with the ANTARES underwater Cherenkov telescope
Cosmic rays were discovered a century ago, but it is still uncertain where or how they are accelerated: since the Universe is opaque to very high energy photons (E > 100 TeV ), traditional astronomy

A reduction in the UHE neutrino flux due to neutrino spin precession
• Physics
• 2012
Abstract Motivated by the stringent flux limits for UHE neutrinos coming from gamma ray bursts or active galactic nuclei, we explore the possibility that the active neutrinos generated in such
Some Current Theoretical Issues around Ultra-High Energy Cosmic Rays
We address some current theoretical issues around ultra-high energy cosmic rays. We recall that scenarios producing more gamma-rays than cosmic rays up to high redshift can in general only provide a
Ultra High Energy Cosmic Radiation: Experimental and Theoretical Status
We give a brief overview of the current experimental and theoretical status of cosmic rays above ~10**17 eV. We focus on the role of large scale magnetic fields and on multi-messenger aspects linking
