Exploring Supernova Neutrinos with DarkSide-20k
ORAL
Abstract
Neutrinos escape the core of a supernova (SN) well before any light, providing crucial insights into stellar core collapse and its mechanisms if detected. Future large scintillator detectors
designed for direct dark matter (DM) searches, such as the next-generation DarkSide-20k experiment, will be sensitive to SN neutrinos through coherent elastic neutrino-nucleus scattering (CEνNS), opening new avenues in the multimessenger study of SN physics.
DarkSide-20k, currently under construction at the Gran Sasso National Laboratory in Italy, features a dual-phase liquid argon time projection chamber with a target mass of ∼50 t, instrumented with a ∼21 m2 surface of silicon photomultipliers for optical readout. While specifically designed for DM detection, DarkSide-20k also holds great potential for discovering SN bursts within our galaxy and beyond, thanks to the analysis techniques developed during the sub-GeV mass-scale DM search. With the experiment veto system in the SN trigger, DarkSide-20k will be sensitive to both the CEνNS, which provides a flavor-blind measurement of the total neutrino flux, and the charged current channel, which measures the electron neutrino component and offers a distinct energy spectrum. These capabilities position DarkSide-20k as a promising tool for advancing our understanding of both SNe and neutrino physics.
