Oscillation Physics at Hyper-Kamiokande

Hyper-Kamiokande is a next generation long baseline neutrino oscillation experiment currently under construction in Japan. The project consists of the Hyper-K detector, which is equipped with newly developed high-sensitivity photo-sensors and has a fiducial mass that is 8.4 times larger than its predecessor, Super-Kamiokande, and a high-intensity neutrino beam produced by an upgraded J-PARC accelerator facility. The Hyper-K detector is both a “microscope,” used to observe elementary particles, and also a “telescope” for observing the Sun and supernovas using neutrinos. In these proceedings we focus on the oscillation measurements including CP violation (𝛿𝐶𝑃) and precision measurement of the $𝜃_{23}$, $𝜃_{13}$ and $Δ𝑚_{23}$ mixing parameters. We also present the current status of Hyper-Kamiokande construction.
