✦ Synopsis
The T2K experiment, which will start in 2009, plans to use the high intensity neutrino beam from J-PARC at Tokai village, Japan. In this talk, we show the physics possibility of putting a 100 kt-level Water Čerenkov detector in Korea during the T2K experimental period. The center of neutrino beam from J-PARC will reach the sea level at the Sea of Japan, and an off-axis beam at 0.5 • to 3.0 • can be observed in Korea. For a combination of the 3 • off-axis beam at SK with baseline length L = 295km and the 0.5 • off-axis beam in the east coast of Korea at L = 1000km, we find that the sign of the larger mass-squared difference can be measured and the CP phase of the MNS matrix can be constrained uniquely at 3-σ level when sin 2 2θrct > ∼ 0.06.
