Ultrahigh Energy Neutrinos at the Pierre Auger Observatory

open access: yesAdvances in High Energy Physics, Volume 2013, Issue 1, 2013., 2013
The observation of ultrahigh energy neutrinos (UHEνs) has become a priority in experimental astroparticle physics. UHEνs can be detected with a variety of techniques. In particular, neutrinos can interact in the atmosphere (downward‐going ν) or in the Earth crust (Earth‐skimming ν), producing air showers that can be observed with arrays of detectors at
