The atmospheric neutrino flux below 100Â MeV: The FLUKA results

We present here the FLUKA results on the atmospheric neutrino flux below 100 MeV, down to 10 MeV. Atmospheric neutrinos in this energy range can be detected by high resolution liquid argon detectors. Below ∼50 MeV, the interaction of these neutrinos are an important background in the searches of relic neutrinos from SuperNovae.
