Title | The Diffuse Supernova Neutrino Background in Super-Kamiokande |
Abstract | Neutrinos have played a key role in astrophysics, from the characterization of nuclear fusion processes in the Sun to the observation of supernova SN1987A and multiple extragalactic events. The Super-Kamiokande experiment has played a major part in past in these astrophysical studies by investigating low energy O(10)~MeV neutrinos, and currently exhibits the best sensitivity to the diffuse neutrino background from distant supernovae. Discovering and characterizing this elusive signal would represent a major breakthrough in astrophysics but also requires state-of-the-art background removal techniques targeting cosmic muon spallation and atmospheric neutrinos. Even in case of an observation, extracting meaningful information about the mechanism of core-collapse supernovae and the history of star formation from a single neutrino spectrum will be a significant challenge. Here, I present an overview of the search for the diffuse supernova neutrino background in Super-Kamiokande and discuss how this signal can be characterized in future experiments, notably in the SuperK-Gd upgrade. |
