Supernova Neutrinos in LENA — •Markus Kaiser, Caren Hagner, Michael Wurm, Björn Wonsak, Daniel Bick, and Sebastian Lorenz — for the LAGUNA-LENA working group - Universität Hamburg, Institut für Experimentalphysik, Luruper Chaussee 149, 22761 Hamburg

The 50 kt liquid scintillator-based detector LENA (Low Energy Neutrino Astronomy) is an option proposed for a next-generation neutrino observatory. The combination of the liquid scintillator technique and huge detector dimensions will allow a high-statistics measurement of the neutrino signal from a core-collapse supernova (SN) within our galaxy. The key goal of studies on SN neutrinos is to measure time- and flavor-dependent features of the neutrino signal.

This talk addresses the event-based neutrino flavor identification for the time-integrated and the time-dependent SN neutrino signal in LENA. A strategy for identifying the neutrino flavor is enabled by the different SN neutrino detection channels provided by LENA. Efficiencies of event discrimination of these detection channels are presented.
