Diffuse supernova neutrinos at underground laboratories
read the original abstract
I review the physics of the Diffuse Supernova Neutrino flux (or Background, DSNB), in the context of future searches at the next generation of neutrino observatories. The theory of the DSNB is discussed in its fundamental elements, namely the cosmological rate of supernovae, neutrino production inside a core collapse supernova, redshift, and flavor oscillation effects. The current upper limits are also reviewed, and results are shown for the rates and energy distributions of the events expected at future liquid argon and liquid scintillator detectors of O(10) kt mass, and water Cherenkov detectors up to a 0.5 Mt mass. Perspectives are given on the significance of future observations of the DSNB, both at the discovery and precision phases, for the investigation of the physics of supernovae and of the properties of the neutrino.

Muonic Boson Limits: Supernova Redux
Supernova models yield coupling limits g_a ≲ 0.9×10^{-10} and g_φ ≲ 0.4×10^{-10} for masses above 100 keV from gamma-ray observations, plus stronger trapping-regime limits from explosion energy, that are difficult to ...

Diffuse Supernova Neutrinos with Secret Neutrino Interactions
Models scalar-mediated νSI on the DSNB in a full three-flavor PMNS framework for four coupling structures and projects 3σ sensitivities at JUNO, Hyper-Kamiokande-Gd, and DUNE reaching g∼10^{-8} for m_ϕ∼100-300 eV.
