Sensitivity for ultra-high-energy neutrinos with the Radio Neutrino Observatory in Greenland (RNO-G)

Résumé fourni par la source

The Radio Neutrino Observatory Greenland (RNO-G) is searching for Askaryan radio signals from ultra-high-energy neutrinos (E>100 PeV) interacting in ice. RNO-G utilizes a hybrid station design, which features radio antennas installed in 100m deep boreholes as well as in hand-digged trenches near the surface. At present, 8 hybrid stations are already operational and collecting science data near the apex of the Greenland ice sheet. The completed observatory will consist of 35 autonomously operating stations deployed over an area of about 50km. Its projected sensitivity will allow to test several models of astrophysical and cosmogenic neutrinos with the potential to detect neutrinos above 100PeV. In this contribution, I will give an overview over the in-ice radio detection of ultra-high-energy neutrinos with RNO-G and present recent estimates of the RNO-G sensitivity.
