Measuring Flavor Ratios of High-Energy Astrophysical Neutrinos
We discuss the prospects for next generation neutrino telescopes, such as IceCube, to measure the flavor ratios of high-energy astrophysical neutrinos. The expected flavor ratios at the sources are
Resonant absorption of cosmic-ray neutrinos by the relic-neutrino background
Within the framework of standard big-bang cosmology and the standard electroweak model, it is shown that ..nu..nu-bar annihilation on the Z resonance is the only cosmic-ray process sensitive to relic
Probing Planck scale physics with IceCube
Neutrino oscillations can be affected by decoherence induced e.g. by Planck scale suppressed interactions with the space-time foam predicted in some approaches to quantum gravity. We study the
TeV γ rays and neutrinos from photodisintegration of nuclei in Cygnus OB2
TeV {gamma}-rays may provide significant information about high energy astrophysical accelerators. Such {gamma}-rays can result from the photo-de-excitation of PeV nuclei after their parents have
Pinning down the cosmic ray source mechanism with new IceCube data
Very recently the IceCube Collaboration has reported an observation of 28 neutrino candidates with energies between 50 TeV and 2 PeV, constituting a 4.1$\sigma$ excess compared to the atmospheric
Decay of high-energy astrophysical neutrinos.
TLDR
This work states that for lifetimes even several orders of magnitude longer, high-energy neutrinos from distant astrophysical sources would decay, which would strongly alter the flavor ratios from the phi(nu(e)):phi-nu(mu):phi(tau)=1-1:1 expected from oscillations alone and should be readily visible in the near future.
