Atmospheric neutrinos as probes of neutrino-matter interactions
Atmospheric neutrinos as probes of neutrino-matter interactions
Neutrino oscillation experiments provide a unique tool for probing neutrino-matter interactions, especially those involving the tau neutrino. We describe the sensitivity of the present atmospheric neutrino data to these interactions in the framework of a three-flavor analysis. Compared to the two-flavor ${\ensuremath{\nu}}_{\ensuremath{\mu}}\ensuremath{-}{\ensuremath{\nu}}_{\ensuremath{\tau}}$ analyses, we find qualitatively new features, in particular, …
