Exotic Neutrino Interactions in Cosmic Rays
Markus Ahlers
The spectrum of extra-galactic cosmic rays (CRs) is expected to follow the Greisen-Zatsepin-Kuzmin (GZK) cutoff at about 5x10^10 GeV which results from energy losses of charged nuc…
Supersymmetry on the Rocks
Markus Ahlers
In R-parity conserving supersymmetric (SUSY) models the lightest SUSY particle (LSP) is stable and a candidate for dark matter. Depending on the coupling and mass of this particle…
Strongly Interacting Neutrinos as the Highest Energy Cosmic Rays: A Quantitative Analysis
Markus Ahlers, Andreas Ringwald, Huitzu Tu
Scattering processes in the cosmic microwave background limit the propagation of ultra high energy charged particles in our Universe. For extragalactic proton sources resonant phot…
Strongly Interacting Astrophysical Neutrinos
Markus Ahlers
The origin and chemical composition of ultra high energy cosmic rays is still an open question in astroparticle physics. The observed large-scale isotropy and also direct compositi…
Cosmic rays at ultra high energies (Neutrinos!)
Markus Ahlers, Andreas Ringwald, Huitzu Tu
Resonant photopion production with the cosmic microwave background predicts a suppression of extragalactic protons above the famous Greisen-Zatsepin-Kuzmin cutoff at about E_{GZK}…
Neutrinos as a diagnostic of cosmic ray Galactic/extra-galactic transition
Markus Ahlers, Luis A. Anchordoqui, Haim Goldberg +3
Motivated by a recent change in viewing the onset of the extra-galactic component in the cosmic ray spectrum, we have fitted the observed data down to GeV and have obtai…
