Energy spectrum unfolding for Supernova burst neutrinos in JUNO — •Thilo Birkenfeld for the JUNO collaboration — RWTH Aachen University

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 measure 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 flavours via different detection channels. The reconstruction of their respective energy spectra requires an effective event classification, whose preliminary results will be presented in this talk. A subsequent bayesian-based energy spectrum unfolding method for reconstructing the initial neutrino energy distribution will also be presented.
