Studying the neutrino mass hierarchy by using the rise time of a supernova signal with LENA — •Markus Kaiser¹, Caren Hagner¹, Björn Wonsak¹, Daniel Bick¹, Sebastian Lorenz¹, and Michael Wurm² — ¹Universität Hamburg — ²Universität Tübingen

LENA (Low Energy Neutrino Astronomy) is a future 50 kt liquid scintillator-based detector. The combination of the liquid scintillator technique and the huge detector dimensions will allow a high-statistics measurement of the neutrino signal from a core-collapse supernova (SN) within our galaxy.

In this talk, one application of a flavor- and time-resolved SN neutrino signal is presented: The investigation of the neutrino mass hierarchy. In LENA, the ν_e signal from a SN can be detected via inverse beta decay at high statistics and with an excellent discrimination efficiency against background. Depending on the neutrino mass hierarchy, the oscillated ν_e signal differs in the rise time of the event rate. The potential to distinguish these signals and therefore the neutrino mass hierarchy is shown in this talk.
