Development of the comprehensive analysis tools for the Supernova neutrino detectors — •Vsevolod Orekhov and Michael Wurm — Institute of Physics and Cluster of Excellence PRISMA+, JGU Mainz, Germany

A galactic Supernova explosion is a unique neutrino source: detecting the neutrinos from deep inside the star will help us understand both the physics of the core collapse and properties of the neutrino themselves. If a SN neutrino burst arrived at Earth today, it would be detected by a variety of ton to kiloton scale neutrino detectors based on different technologies and target media. A full understanding of the observed signals can only be obtained by a combined analysis of the different interaction channels. This contribution presents an analysis framework developed to combine and fit the neutrino spectra from different detectors assuming a common flavour-dependent neutrino signal. We start the development from the six channels available on hydrogen, carbon and electrons that are available in large liquid scintillator detectors like JUNO. From there, the framework will be extended to include other detector types.
