Muon veto restriction with Topological Track Reconstruction in JUNO — •David Meyhöfer, Henning Rebber, Malte Stender, and Björn Wonsak — Institut für Experimentalphysik, Universität Hamburg, Germany

The main signal at Jiangmen Underground Neutrino Observatory (JUNO) is the inverse beta decay (IBD) and the muon veto has the largest impact on IBD efficiency. Therefore an improvement of the muon veto strategy can yield more active volume, which in turn will enable more signal in the same time or the same signal in less measurement time. This talk will focus on the reduction of dead volume in JUNO with the restriction of muon vetoes to points of interest along muon tracks. This method is enabled by the reconstruction capabilities of the topological track reconstruction approach, which can determine shower positions along muon tracks.
