Neutrinos are produced in large quantities in core-collapse supernovae. However, to this date, the observation of supernovae through neutrino detection has been limited to a single event, SN1987A. Another possibility for studying supernova neutrinos is through the detection of the Diffuse Supernova Neutrino Background (DSNB), which represents the collective flux of neutrinos emitted by all...
The discovery of nonzero neutrino masses naturally leads to the consideration of heavier neutrinos decaying into lighter ones. We explore the impact of two-body neutrino decays on the neutronization burst of a core-collapse supernova—the intense burst of electron neutrino emission occurring within the first 25 ms after the core bounce. In the scenario considered, the electron neutrinos are...
