Description
Super-Kamiokande (SK) has been operational since 1996, revealing neutrino oscillations and precisely measuring oscillation parameters. With the extensive atmospheric neutrino data collected, we have recently been exploring the neutrino mass hierarchy. In 2020, gadolinium was added to the SK tank, and since then, we have been collecting data with neutron tagging information. One of the most intriguing subject of the Gd-loaded Super-K is the search for the diffuse supernova neutrino background. In addition, performance of galactic supernova detection has been improved. This presentation covers the latest physics results from the long-term SK operation and the recently obtained Gd-loaded data.
