Observing supernova neutrino light curve in future dark matter detectors

Understand

The possibility of observing supernova (SN) neutrinos through the process of coherent elastic neutrino-nucleus scattering (CENNS) in future ton scale detectors designed primarily for direct detection of dark matter is investigated.

• In particular, we focus on the possibility of distinguishing the various phases of the SN neutrino emission.
• The neutrino emission rates from the recent long term Basel/Darmstadt simulations are used to calculate the expected event rates.
• The recent state-of-the-art SN simulations predict closer fluxes among different neutrino flavors and lower average energies compared to the earlier simulation models.
