Event selection and spectrum unfolding for Supernova burst neutrinos in JUNO — •Thilo Birkenfeld, Achim Stahl, Jochen Steinmann, and Christopher Wiebusch — RWTH Aachen University

No core-collapse supernova (CC-SN) exploded close enough to be observed by terrestrial neutrino telescopes since the first detection of neutrinos from SN 1987A. The Jiangmen Underground Neutrino Observatory (JUNO) is a next-generation liquid scintillator detector with a large target mass of 20 kt. It will provide valuable insight into the details of the SN mechanism by observing the neutrino burst of a galactic CC-SN with high statistics and an unpreceded energy resolution of 3 % @ 1 MeV. JUNO will be sensitive to signals from all neutrino flavors via different detection channels. The reconstruction of their respective energy spectra requires an effective event classification. In this talk, we will present the results of an event classification and a subsequent Bayesian-based energy spectrum unfolding.
