Description
The Payload for Ultrahigh Energy Observations (PUEO) experiment is an Antarctic balloon-borne detector targeting astrophysical neutrinos with energies exceeding 100 PeV. PUEO aims to observe neutrinos via the detection of coherent radio emission sourced from in-ice neutrino interactions. The dominant channel for these interactions is the charged current interaction, which produces both a recoiling nuclei and the corresponding charged lepton to the flavor of the parent neutrino. At high energies, both of these particles are capable of developing in-ice particle cascades, with the charged lepton capable of producing multiple secondary cascades through radiative losses in the ice. We model the radio emission from these multi-cascade events as it would be observed during PUEO’s flight and quantify the signal properties, providing an outlook on PUEO’s ability to make flavor measurements of neutrinos at the highest energies.
