Description
Core Collapse Supernovae (CCSN) are explosive phenomena that may occur at the end of
the life of massive stars, releasing over 99% of the energy through emission of MeV
neutrinos. Neutrinos are believed to play an important role in the not yet fully understood
explosion mechanism. Only 24 SN neutrinos have been detected from the SN1987A event.
For a galactic CCSN, the KM3NeT ORCA and ARCA detectors in the Mediterranean will
observe a significant number of neutrinos via Cherenkov light, mostly from inverse beta
decay interactions in a large seawater volume. Selection of coincidences between the 31
photomultipliers of KM3NeT optical modules allows to separate the signal from the optical
background sources.
The KM3NeT sensitivity for the detection of a galactic CCSN and the potential for the study
of the burst time profile have been estimated from MC simulations. Specific criteria are
proposed for the online triggering and the participation in the SNEWS global alert network.
