Topological track reconstruction for Borexino — •Björn Opitz1, Björn Wonsak1, Daniel Bick1, Sebastian Lorenz2, and Michael Wurm21Universität Hamburg, Institut für Experimentalphysik — 2Johannes Gutenberg-Universität Mainz, Institut für Physik

In unsegmented liquid scintillator detectors like Borexino, signal and background events are recorded by measuring the scintillation light from charged particle interactions in the detector volume. A novel event reconstruction technique, currently being developed at several German institutes, allows an improved reconstruction of track topologies within the detector (see the overview talk by Sebastian Lorenz, Uni Mainz). In particular, particle showers induced by cosmic muons can be identified and analyzed. Up to now, the method has been implemented and used for Monte Carlo studies concerning the planned experiments LENA and JUNO. Adopting the reconstruction technique for Borexino allows the use of real data and a comparison with standard reconstruction methods for both neutrino and muon events. The current status of the implementation is presented.
