A novel view at using the topological track reconstruction in JUNO — •Mikhail Smirnov, Daniel Bick, Milo Charavet, Caren Hagner, and Rosmarie Wirth — Institute of Experimental Physics, University of Hamburg, Hamburg, Germany

The Jiangmen Underground Neutrino Observatory (JUNO) represents a new generation of kiloton-scale neutrino detectors based on liquid scintillator (LSc). With a target mass of 20 kilotons, it will be the largest LSc detector in the world. Utilizing the antineutrino flux from two nuclear power plants at a baseline of approximately 53 km, JUNO aims to determine the neutrino mass ordering with at least 3σ significance and to make precise measurements of oscillation parameters. Initially, the topological track reconstruction (TTR) was developed to reconstruct muon events in unsegmented LSc detectors for particles with energies up to 10 GeV. This reconstruction algorithm uses time and spatial information from PMT hits to iteratively determine the origin and trajectory of particles inside the detection medium. This talk reviews the TTR method and its potential applications in the JUNO experiment and is supported by the DFG.
