Description
The Hyper-Kamiokande (HK) experiment will be the next crucial step in the Kamiokande series, and it will lead its own search for the Diffuse Supernova Neutrino Background (DSNB). This yet-detected signal from all past core-collapse supernova has been pursued by HK's predecessor, Super-Kamiokande. HK can provide not only a confirmation of a DSNB signal but also new, complementary information thanks to its large fiducial volume. Here, we show sensitivity to the DSNB in HK as a function of neutrino energy, and we discuss possible improvements to target and barriers to overcome.
