| Outline of Final Research Achievements |
Super-Kamiokande was upgraded to be able to distinguish between electron and antielectron neutrinos, and a search for diffuse supernova neutrino background(DSNB) with antielectron neutrinos was performed with the highest sensitivity in the world. As a result, although we did not detect DSNB, we succeeded in placing the world's most stringent limit on the flux of DSNB, as expected. In addition, the detection of neutrinos at the time of the supernova explosion improved the accuracy of determining the direction of the supernova explosion.
