Advances of the topological track reconstruction for large unsegmented liquid scintillator neutrino detectors. — •David Meyhöfer for the JUNO collaboration — University of Hamburg

The track reconstruction of charged particles in liquid scintillator (LS) detectors is of utmost importance for efficient cosmogenic background rejection and the analysis of multi-GeV neutrino interactions. A topological reconstruction of such events yields the possibility of gaining a 3D density distribution of the emitted scintillation and/or cherenkov photons. This reconstruction approach can in principle be used for any geometry of unsegmented LS detector and for MeV- up to several GeV-events. In association with the JUNO experiment in China, this topological reconstruction method is developed in Germany. With simulated muon events, this method has shown, that the particles differential energy loss dE/dx is obtainable. This talk will give an overview over the recent developments and the current status for this reconstruction approach.
