Reconstruction and selection of Supernova burst neutrinos in JUNO — •Thilo Birkenfeld, Achim Stahl, and Christopher Wiebusch — RWTH Aachen University - Physics Institute III B, Aachen, Germany

Since the detection of neutrinos emitted by the supernova SN 1987A, no neutrinos from other supernovae have been observed to date. The Jiangmen Underground Neutrino Observatory (JUNO) will be capable of measuring the neutrino burst from a galactic supernova explosion. High statistics, a low detection threshold, and an excellent energy resolution will strongly constrain the details of the neutrino-driven supernova mechanism. JUNO will be sensitive to signals from all neutrino flavors via different detection channels. These comprise of the inverse beta decay, elastic scattering on protons and electrons, and various interactions with carbon. Separating these channels is challenging but crucial for flavor dependent analyses of the supernova burst. We present preliminary results of an event classification based on a full detector simulation including energy and vertex reconstruction.
