The precise reconstruction of charged particle tracks in unsegmented liquid scintillator (LSc) neutrino detectors, e.g., from muons, is an important prerequisite for the efficient rejection of cosmogenic background events or the analysis of multi-GeV neutrino interactions. Topological information on such events, i.e., the reconstructed 3D density distribution of isotropically emitted scintillation photons, opens up new ways to accomplish these tasks. Especially future multi-kiloton LSc detectors will profit from improved (muon) track reconstruction possibilities, both regarding their low- and high-energy neutrino physics programs. Connected to the international JUNO project in China, a topological track reconstruction method for unsegmented LSc detectors is developed in Germany. Its application to simulated muon events already showed that the particle’s differential energy loss dE/dx is accessible. This talk summarizes recent developments and the current status of the reconstruction method.
