Improving Measurement of Astrophysical Neutrino Flux with Advanced Northern Tracks Selection in IceCube — •Shuyang Deng, Lasse Düser, Sönke Schwirn, Philipp Soldin, Christopher Wiebusch, and Marco Zimmermann — III. Physikalisches Institut B RWTH Aachen University, Aachen, Germany

The IceCube Neutrino Observatory is a large neutrino detector at the South Pole. One of its main detection channels is via neutrino-induced muon tracks, which provide a large effective area and high angular resolution. The Advanced Northern Track Selection (ANTS) framework uses a graph convolutional neural network to improve the selection of these events, as well as to perform reconstructions of their physical parameters. Furthermore, these events show different topologies and signatures within the detector, which can be classified with ANTS, enabling dedicated handling of these topologies in analyses. In this talk, we will show the performance of ANTS and the improvement in sensitivity it provides for the measurement of the astrophysical neutrino flux.
