“…The lower value is set by the detector response and the upper value is set by the falling DSNB spectrum. This range is comparable to that for prior and future searches for DSNB νe [42,43,46], DSNB ν e [48][49][50][51], and DSNB ν x [52]. Typically, experiments note the range of detected (not emitted) energies they probe.…”

“…But our understanding of core collapse depends on probing the DSNB is all flavors, which is hard. For ν e , the Sudbury Neutrino Observatory (SNO) has set a limit 19 cm −2 s −1 [48,49], and the Deep Underground Neutrino Experiment (DUNE) should improve on this [50,51]. The weakest link is ν x , i.e., each of ν µ , ν τ , νµ , ντ .…”

Fully understanding the average core-collapse supernova requires detecting the diffuse supernova neutrino background (DSNB) in all flavors. While the DSNB νe flux is near detection, and the DSNB νe flux has a good upper limit and promising prospects for improved sensitivity, the DSNB νx (each of νµ, ντ , νµ, ντ ) flux has a poor limit and heretofore had no clear path for improved sensitivity. We show that a succession of xenon-based dark matter detectors -XENON1T (completed), XENONnT (under construction), and DARWIN (proposed) -can dramatically improve sensitivity to DSNB νx the neutrino-nucleus coherent scattering channel. XENON1T could match the present sensitivity of ∼ 10 3 cm −2 s −1 per νx flavor, XENONnT would have linear improvement of sensitivity with exposure, and a long run of DARWIN could reach a flux sensitivity of ∼ 10 cm −2 s −1 . Together, these would also contribute to greatly improve bounds on non-standard scenarios. Ultimately, to reach the standard flux range of ∼ 1 cm −2 s −1 , even larger exposures will be needed, which we show may be possible with the series of proposed lead-based RES-NOVA detectors.

“…Understanding of cosmogenic [92] and radiological backgrounds is also necessary for determination of low-energy event reconstruction quality and for setting detector requirements. The dominant radiological is expected to be 39 Ar, which β decays at a rate of ∼1 Bq/liter, with an endpoint of <1 MeV.…”

The deep underground neutrino experiment (DUNE), a 40-kton underground liquid argon time projection chamber experiment, will be sensitive to the electron-neutrino flavor component of the burst of neutrinos expected from the next Galactic core-collapse supernova. Such an observation will bring unique insight into the astrophysics of core collapse as well as into the properties of neutrinos. The general capabilities of DUNE for neutrino detection in the relevant few- to few-tens-of-MeV neutrino energy range will be described. As an example, DUNE’s ability to constrain the $$\nu _e$$ ν e spectral parameters of the neutrino burst will be considered.

The diffuse supernova neutrino background (DSNB) is a powerful future tool to constrain core-collapse explosion mechanisms without observation of a nearby event, and the corresponding signal has been calculated for a variety of collapse models. For Supernova (SN) 1987A, a peculiar double neutrino burst was detected, but models for the double collapse have never been studied in the DSNB context. Here, we fill this gap and compare the DSNB signal expected in the Standard Collapse (SC) and the Double Collapse (DC) models in various future detectors, including Hyper-Kamiokande, JUNO, DUNE and the Large Baksan Neutrino Telescope (LBNT). We calculate the spectra of diffuse neutrinos and antineutrinos in the DC model and determine the rate of registered events as a function of energy of the detected particle, taking into account detector parameters. For each detector, we estimate the corresponding uncertainties and the background and compare the signals expected for the SC and DC models. We conclude that the combination of DUNE and LBNT data will have the highest sensitivity to discriminate between the SC and DC models.
