Abstract
The Diffuse Supernova Neutrino Background (DSNB) is the collection of neutrinos from all core-collapse supernovae (CCSNe) since the beginning of the universe. It is sensitive to the universe's stellar formation history, the fraction of CCSNe forming black holes, and cosmological expansion. To this date, it has yet to be detected. The most sensitive experimental search is from the Super-Kamiokande experiment, and the next few years will see other sensitive experiments like Hyper-Kamiokande and the Jiangmen Underground Neutrino Observatory come online. Here, we summarize the latest results and sensitivity for the DSNB search as well as its potential to probe new physics.
