Description

The IceCube Neutrino Observatory is a Cherenkov detector instrumenting over a cubic kilometer of Antarctic ice. The main IceCube array can detect high-energy neutrino emissions from astrophysical sources, while the denser-configured subdetector (DeepCore) can observe down to GeV-scale neutrinos, which improves the sensitivity to measure the disappearance of atmospheric muon neutrinos. For precise and rapid reconstructions, machine-learning techniques are employed. This talk presents a new measurement of $\Delta m^2_{32}$ and $\sin^2(\theta_{23})$ using 9.3 years of atmospheric neutrino data compared to existing results from other experiments.
