Reconstruction Methods for In-Situ Radio Neutrino Detectors

Ultra-high energy (UHE) neutrinos are unique messengers to the distant universe, as gamma rays and cosmic rays do not arrive unattenuated or undeflected. A promising way to detect these UHE neutrinos is through the radio Cherenkov emission produced by neutrino-nucleon interactions in transparent media like ice. Several experiments are operating, under construction, or planning to observe neutrinos through this method, such as ARA, ARIANNA, RNO-G, and IceCube-Gen2. In this talk, we will discuss development of methods for reconstructing key properties of the neutrino interaction for in-situ neutrino detectors, including the vertex position and shower energy. These methods are based on simulations of a “deep” detector, with instrumentation deployed >100m. Reconstruction of the signal polarization, which is also a key measurement, is considered in a separate contribution.
