Ultrahigh Energy Neutrinos at the Pierre Auger Observatory
Figure 3
Pictorial representation of the different types of inclined showers that can be detected at the surface detector array of the Pierre Auger Observatory. An inclined shower induced by a proton interacting high in the atmosphere whose electromagnetic component is absorbed and only the muons reach the detector. Inclined showers presenting significant electromagnetic component at the detector level: a deep downward-going -induced shower; an Earth-skimming interacting in the Earth crust and producing an upward-going lepton that decays in flight and induces a shower in the atmosphere; and a interacting in the mountains, producing a downward-going lepton that decays close to the detector and initiates a shower.
