Abstract:
\nHyper-Kamiokande is a next generation large scale neutrino detector in Japan with a
\nfiducial volume of 187 kton. Neutrinos from J-PARC accelerator provides high
\nstatistics measurement of 3% accuracy in both neutrinos and anti-neutrinos beams
\ntuned at the first oscillation maximum. Atmospheric neutrinos provide high statistics
\nneutrino oscillation studies up to several oscillation maxima, which is called
\noscillogram. Careful control of systematic uncertainties is essential to match the
\nhigh statistical precision. Taking the ratios between near and far detectors in the
\naccelerator neutrinos would cancel the systematic uncertainties in principle, but
\nthere remains challenging difference in the energy and neutrino flavour (electron vs.
\nmuon neutrinos) dependence of cross sections and the difference in detection
\nefficiencies between near and far detectors. In this talk, I will describe the approach
\ntaken by Hyper-Kamiokande to carefully cancel and control the systematic
\nuncertainties. The high precision expands HyperK\u2019s sensitivity to neutrino
\nastrophysics, such as the supernova neutrinos and higher energy astronomical
\nneutrinos, as well as the searches for dark matters and nucleon decays.<\/p>\n
