Physics Potentials of the Hyper-Kamiokande Second Detector in Korea

Abstract

Hyper-Kamiokande (Hyper-K) succeeds the very successful Super-K experiment and will consist of a large detector filled with 260~kton purified water and equipped with 40\% photo-coverage. Physics program of Hyper-K is broad, covering from particle physics to astrophysics and astronomy. The Hyper-K 1${}^{st}$ detector will be built in Japan, and the 2${}^{nd}$ detector is considered to be built in Korea because locating the 2${}^{nd}$ detector in Korea improves physics sensitivities in most cases thanks to the longer baseline ($\sim$1,100~km) and larger overburden ($\sim$1,000~m) for Korean candidate sites. In this talk, we present overview and physics potentials of the Hyper-K 2${}^{nd}$ detector in Korea.
