Description
The Hyper-Kamiokande (Hyper-K) is a next generation long baseline neutrino experiment. The Hyper-K water Cherenkov far detector is designed to succeed the Super-Kamiokande (SK) detector. Currently under construction in Japan, the construction and commissioning of the experiment is expected to be finalized by the end of 2027, with data-taking starting in 2028. Compared to its predecessors, the Hyper-K far detector extended capabilities will amount to a fiducial volume nearly one order of magnitude higher (260 kton total, 190 kton fiducial). It will be instrumented with 20000 high-efficiency 50 cm photodetectors, 1000 multi-photodetectors, electronics and DAQ, that associated with new calibration and monitoring approach, with deliver a broader spectrum of measurement possibilities and higher level of data quality when compared to existing data. Combined with a MegaWatt-class beamline located at the J-PARC accelerator facility and a complex of near and intermediate detectors, the experiment will collect unprecedented number of neutrino interactions for a very broad physics program that includes: the discovery of CP-violation in the lepton sector; precise measurements of neutrino flavor oscillation parameters; testing of Grand Unified Theories with proton decay search; probing for new physic scenarios in the upturn region of solar neutrinos; constraining supernova mechanisms and cosmic star-formation history by observing neutrinos from both individual and diffuse supernova sources (DSNB). The advancement status of Hyper-K far and near detectors including the Intermediate Water Cherenkov Detector (IWCD) will be reported in this presentation, along with its physics goals.
