Outline of Final Research Achievements

T2K experiment is a long baseline neutrino experiment using high quality neutrino beam generated at J-PARC and Super-Kamiokande as the far detector. T2K obtained a definitive results on electron neutrino appearance. That is a breakthrough to measure the neutrino CP symmetry which could explain the matter dominant universe.
This study aims to improve the measurement precision of electron neutrino appearance, in order to measure the CP symmetry first time, by carrying out detailed SK detector calibrations and by improving the SK event reconstruction algorithm based on the calibration results.
