Flavor differentiation for in-ice radio neutrino detectors — •Janna Vischer for the RNO-G collaboration — Erlangen Centre for Astroparticle Physics, Erlangen, Germany

Cosmogenic neutrinos (> PeV) can be detected via the Askaryan effect when they interact and induce particle showers in ice. The thereby created radio signals can be observed using large scale antenna arrays. This is currently done at the Radio Neutrino Observatory Greenland (RNO-G) and planned for the radio component of IceCube-Gen2. The capability to differentiate neutrino flavors would be an asset for such experiments. In the event of deep-inelastic scattering, neutrino interactions produce either an undetectable neutrino (neutral-current interaction) or an electron, muon, or tau lepton (charged-current interaction), both occasionally accompanied by measurable hadronic showers. In the second case extremely high energetic muons and taus themselves radiate secondary showers along their tracks. Particle showers with an energy above PeV can be detected. In this contribution we investigate how the signatures of these secondary showers can be used to deduce the flavor of the original neutrino in radio neutrino detectors.
