New reconstruction method for liquid scintillator. First results for muon tracks

An efficient veto-based rejection of muon-induced background is an important prerequisite for experiments in low-energy neutrino physics. For unsegmented liquid scintillator detectors, common tools in this field, this requires the precise reconstruction of muon tracks within the active volume based on the isotropically emitted scintillation photons. A novel reconstruction technique for this challenging task, which could be employed in the future large-volume detector of JUNO, is in development. The method aims to reconstruct the 3D number density distribution of photon emissions, which reflects an event's geometry and topology. Based on single muons simulated in the LENA detector, first results on the method's performance are presented.
