Observation of neutrinos with JEM-EUSO: an updated view

Abstract

Similarly to extreme energy cosmic rays (EECRs), neutrinos at energies exceeding 5×10 19 eV are expected to interact in the Earth's atmosphere and create extensive air showers. The JEM-EUSO mission, developed to be hosted onboard the JEM module of the International Space Station, aims at detecting these extensive air showers from space by means of the fluorescent and diffusively reflected Cherenkov light they produce. In the present paper we investigate the capability of JEM-EUSO to trigger and detect neutrino induced events in the H-II Transfer Vehicle (HTV) configuration. We also discuss the status of their reconstruction feasibility considering JEM-EUSO's most recent design, which will be launched with Falcon 9 and delivered to the ISS by the SpaceX Dragon free-flying spacecraft.

The JEM-EUSO Program

“…Space debris are widely recognized as one of the growing threads against space operations. Detailed studies on the capability of JEM-EUSO on UHE neutrino and photon detection can be found in [14], [15].…”
