I will discuss uncertainties in our knowledge of the flux of atmospheric neutrinos. At low energies relevant for study of neutrino oscillations, primary sources of uncertainty are related to properties of hadronic physics, such as the kaon to pion ratio. Around 100 TeV the uncertain level of charm production becomes important. The primary spectrum, which dominates the normalization of the...

Neutrino flavor oscillations in matter moving with a constant speed and in matter moving with acceleration are considered. The corresponding generalizations of the Mikheyev-Smirnov-Wolfenstein resonance condition is evaluated. The results are of interest for astrophysical applications. In particular, it is shown that the matter motion and acceleration significantly contribute to the neutrino...

IceCube is accumulating an unprecendented number of contained neutrino events with energies from 1 TeV to beyond 100 TeV. The neutrinos at the lower end of the energy range come from the decays of pions and kaons produced in air showers; the energy spectrum is roughly one power steeper than the cosmic ray flux, and muon neutrinos dominate. At higher energies, however, the flavor ratio begins...

The ANTARES neutrino telescope, situated off the French coast at about 2500m depth in the Mediterranean Sea, is optimized to detect charged leptons induced by neutrinos in the TeV range. Since its full deployment in 2008, various direction and energy reconstruction techniques have been developed and applied in the search for a diffuse flux of astrophysical neutrinos. In this talk, the results...

The IceCube Neutrino Observatory routinely records thousands of muon neutrino events per year at TeV and higher energies. The majority of these neutrinos are produced in Earth's atmosphere by cosmic ray interactions, but it is of great interest to observe a population of events consistant with astrophysical origin. This talk will discuss a search for a hard component in the muon neutrino...
