High-energy neutrino oscillations in absorbing matter

The impact of neutrino mixing, refraction and absorption on high-energy neutrino propagation through a thick medium is studied using the MSW evolution equation with complex indices of refraction. It is found that, owing to the mixing with sterile neutrinos, the penetrability of active neutrinos may be many orders of magnitude larger than it would be in the absence of mixing. The effect is highl...

Neutrino oscillations in high energy cosmic neutrino flux

I discuss the effects of neutrino oscillations on high energy cosmic neutrinos which come from cosmologically distant astrophysical sources. I incorporate all the up-to-date constraints from the solar, atmospheric, reactor, accelerator data and give the possible pattern for the ratio of the high energy cosmic neutrinos in the cases of three and four neutrino schemes.

Neutrino Oscillations at High Energy by MACRO

We present updated results of the measurement of upward-going muons produced by neutrino interactions in the rock below the MACRO detector. These data support MACRO’s previously published results. They favor a neutrino oscillation explanation of the atmospheric neutrino anomaly.

Neutrino Oscillations and Dark Matter

The significance of light massive neutrinos as hot dark matter is outlined. The power of neutrino oscillation experiments with respect to detect such neutrinos in the eV-region is discussed. Present hints for neutrino oscillations in solar, atmospheric and LSND data are reviewed as well as future experiments and their potential.
