Presupernova neutrinos in large dark matter direct detection experiments

Abstract: The next Galactic core-collapse supernova (SN) is a highly anticipated observational target for neutrino telescopes. However, even prior to collapse, massive dying stars shine copiously in "presupernova" (pre-SN) neutrinos, which can potentially act as efficient SN warning alarms and provide novel information about the very last stages of stellar evolution. We explore the sensitivity to pre-SN neutrinos of large scale direct dark matter detection experiments, which, unlike dedicated neutrino telescopes, take f… Show more

“…It is also worthwhile to mention that the large dark-matter detectors could also record pre-SN neutrinos via the coherent neutrino-nucleus scattering [64]. Given a rather simple picture of flavor conversions for the pre-SN neutrinos, the luminosities, average energies and flavor content of the original pre-SN neutrinos could be unveiled with a good opportunity after combining different reaction channels in the neutrino detectors and even the pre-SN neutrino events in the dark-matter detectors.…”

“…Large dark matter experiments may potentially detect pre-SN neutrinos because of the combination of very low detection thresholds (around or below the keV level) and CEνNS (19). One advantage in these experiments is a sensitivity to all six flavors of neutrinos, from which complementary observations of pre-SN neutrinos are expected.…”

“…Second, the observation of pre-SN neutrinos serves as an alarm (SN alarm) regarding the subsequent explosion and makes it possible to observe the next galactic SN. The neutrinos may be detected a few days before the explosion if the progenitor is located in our vicinity (<1 kpc) (16,19). It is supposed that galactic SNe occur once every few hundred years.…”

“…In particular, for stars within ∼ 1 kpc of Earth like Betelgeuse, presupernova neutrinos will be detected at multi-kiloton neutrino detectors like the current KamLAND (see Araki et al (2005) for a dedicated study), Borexino (Borexino Collaboration et al 2018), SNO+ (Andringa et al 2016), Daya Bay (Guo et al 2007) and Su-perKamiokande (Simpson et al 2019), and the upcoming HyperKamiokande (Abe et al 2016), DUNE (Acciarri et al 2016) and JUNO (An et al 2016;Li 2014;Brugière 2017). Next generation dark matter detectors like XENON (Newstead et al 2019), DARWIN (Aalbers et al 2016), and ARGO (Aalseth et al 2018) will also observe a significant signal (Raj et al 2020). Therefore, presupernova neutrinos are a prime target for the SuperNova Early Warning System network (SNEWS, Antonioli et al 2004) -which does or will include the neutrino experiments mentioned above -and its multimessenger era successor SNEWS 2.0, whose mission is to provide early alerts to the astronomy and gravitational wave communities, and to the scientific community at large as well.…”
