A novel method of rejecting muon backgrounds for the detection of the highest energy neutrinos
2019 July 22
The IceCube neutrino observatory, located at the South Pole, has discovered the astrophysical diffuse flux and multi-PeV neutrino events. The 10-100 PeV energy range is key to test the possible common origin of IceCube neutrinos and ultra-high energy cosmic rays. In this work,we present a new analysis targeting at cascade-like showers of deposit energy 10-100 PeV. The new event selection is sensitive to both contained and partially-contained cascades.
