IceCube Collaboration, 2012Collaboration, , 2017)), KM3NeT (KM3NeT 2016), and Baikal-GVD (Baikal-GVD 2018) have the science goal of detecting neutrinos measuring their properties origins.Reconstruction at these experiments is concerned with classifying type event or estimating interaction.

IceCube DeepCore, the existing low-energy extension of Neutrino Observatory, was designed to lower neutrino detection energy threshold GeV range. A new extension, called Upgrade, will consist seven additional strings installed within DeepCore fiducial volume. The modules have spacings about 20 m horizontally and 3 vertically, compared 40-70 7 vertically in DeepCore. It be deployed polar season 2025/26. This hardware features types optical with multi-PMT configurations, as well calibration...

The DeepCore detector is a densely instrumented sub-array of the IceCube Neutrino Observatory designed to observe atmospheric neutrino interactions above 5 GeV via Cherenkov radiation in Antarctic ice. At these energies, Earth-crossing muon neutrinos have high chance oscillating tau neutrinos. These oscillations been previously observed through both disappearance and appearance. While able measure with precision comparable accelerator-based experiments, it also complements accelerator...

Abstract The DeepCore sub-array within the IceCube Neutrino Observatory is a densely instrumented region of Antarctic ice designed to observe atmospheric neutrino interactions above 5 GeV via Cherenkov radiation. An essential aspect any oscillation analysis ability accurately identify flavor events in detector. This task particularly difficult at low energies when very little light deposited Here we discuss use machine learning perform event classification using boosted decision tree (BDT)....
