Abstract

The IceCube Neutrino Observatory has detected astrophysical neutrinos with energies ranging from a few TeV to multiple PeV. To extend the energy range beyond 10 PeV, we combine throughgoing tracks from the northern sky, high-energy starting tracks, contained cascades and uncontained cascades from the entire sky. This extension is critical for testing models that predict a common origin for ultra-high-energy cosmic rays (UHECRs) and neutrinos. We present our analysis, designed to achieve the highest sensitivity to the PeV neutrino flux through advanced modeling of atmospheric backgrounds, refined ice systematics, and improved energy resolution in event reconstructions enabled by a combination of machine learning and likelihood-based techniques.
