D.Fargion, D. D'Armiento
TL;DR
This paper discusses the emerging field of ultra-high-energy cosmic ray and neutrino astronomy, highlighting potential discoveries, the role of tau neutrinos, and how different UHECR compositions influence neutrino detection prospects.
Contribution
It provides an analysis of how UHECR composition affects tau neutrino detection and predicts the potential of upcoming observatories to identify neutrino flavors.
Findings
Tau neutrinos may be the first flavor detected in UHE astronomy.
UHECR composition influences the energy range of detectable tau neutrinos.
Upcoming detectors like AUGER's denser arrays could observe these neutrinos within a few years.
Abstract
Photon Astronomy ruled the last four centuries while wider photon band ruled last radio-X-Gamma century of discovery. Present decade may see the rise and competition of UHECR and UHE Neutrino Astronomy. Tau Neutrino may win and be the first flavor revealed. It could soon rise at horizons in AUGER at EeV energies, if nucleons are the main UHECR currier. If on the contrary UHECR are Lightest nuclei (He, Li. B) UHE tau neutrino maybe suppressed at EeV and enhanced at tens -hundred PeV. Detectable in AMIGA and HEAT denser sub-array in AUGER. Within a few years.
