An Upper Limit on the Electron‐Neutrino Flux from the HiRes Detector
An Upper Limit on the Electron‐Neutrino Flux from the HiRes Detector
Air-fluorescence detectors such as the High Resolution Fly's Eye (HiRes) detector are very sensitive to upward-going, Earth-skimming ultrahigh energy electron-neutrino-induced showers. This is due to the relatively large interaction cross sections of these high-energy neutrinos and to the Landau-Pomeranchuk-Migdal (LPM) effect. The LPM effect causes a significant decrease in the …
