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 νe 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 νe 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.
