Description

The IceCube Neutrino Observatory is located at the geographic South Pole instrumenting a cubic kilometer of deep glacial ice with 5,160 digital optical modules on the main array to detect Cherenkov light. The DeepCore sub-detector is a denser in-fill array that gives a lower energy threshold where we can study neutrino oscillations using atmospheric neutrinos with energies of 5-100 GeV. Precisely reconstructing neutrino energy and arrival direction is critical to constraining oscillation parameters. Convolutional neural networks are employed for precise and fast event reconstructions. In this contribution, using IceCube data collected from 2012 to 2021, including the latest improvements in reconstruction, selection, detector calibration, and treatment of systematic uncertainties, we present our most recent measurement of sin^2(\theta_{23}) and \Delta m^2_{32}.
