Physics potentials with the second Hyper-Kamiokande detector in Korea
/ Abe, K ; Abe, Ke ; Ahn, S H ; Aihara, H ; et al
Hyper-Kamiokande consists of two identical water-Cherenkov detectors of total 520 kt, with the first one in Japan at 295 km from the J-PARC neutrino beam with 2.5 off-axis angles (OAAs), and the second one possibly in Korea at a later stage. [...]

First Evidence for and Resolution of the Cabibbo-Kobayashi-Maskawa Quark-Mixing Unitarity Triangle Ambiguity
/ Adachi, I. ; Adye, T. ; Ahmed, H. ; Ahn, J. K. ; et al
We present first evidence that the cosine of the -violating weak phase is positive, and hence exclude trigonometric multifold solutions of the Cabibbo-Kobayashi-Maskawa (CKM) Unitarity Triangle using a time-dependent Dalitz plot analysis of with decays, where denotes a light unflavored and neutral hadron.
