Summary:

Abstract: Diffuse supernova neutrino background (DSNB) as the integrated flux from all past core-collapse supernova explosions, if detected, would be a probe to explore the supernova mechanism as well as stellar evolution. In this talk, I will present a short review of theoretical and experimental status of the DSNB studies and a recent search result from Super-Kamiokande with an improved sensitivity. The presentation will be based on arXiv:2109.11174.
