Ultrahigh Energy Neutrino Detection with the Payload for Ultrahigh Energy Observations (PUEO) Experiment

Neutrinos are unique astrophysical messengers that interact only through the weak force and so can travel cosmological distances without interacting. Ultrahigh Energy (UHE) neutrinos (≥1 EeV) can be detected through radio frequency (RF) signals. UHE neutrinos can initiate a particle shower that emits coherent Cherenkov radiation in a dense dielectric medium and can thus be detected by antennas viewing radio transparent cold ice in the Antarctic Ice Sheet. The Payload for Ultrahigh Energy Observations (PUEO) experiment will employ broadband radio interferometric techniques to detect these radio signatures. The experiment aims to either detect a UHE neutrino or provide further constraints on the neutrino flux at the highest energies.
