Description
The Diffuse Supernova Neutrino Background (DSNB) is a theoretical astrophysical prediction of a collection of neutrinos from all core-collapse supernovae that ever existed in the Universe. It is yet to be observed. This presentation will showcase the latest results from the gadolinium-loaded Super-Kamiokande (SK) experiment and how it excludes certain theoretical models. While SK is primarily sensitive to the integrated value of the DSNB flux, the future Hyper-Kamiokande (HK) experiment will probe the shape of the spectrum in more detail. A study of HK sensitivity to relevant parameters, such as the fraction of black hole forming supernovae, will then be presented. Finally, the discussion will delve into how the observation of a nearby supernova could better constrain the DSNB models by measuring the supernova neutrino emission spectrum.
