| Outline of Final Research Achievements |
Aim of this study is to search for sterile neutrino in unsolved parameter region with Double Chooz detectors, measuring energy spectrum of anti-neutrino with 400 m and 1 km baseline from Chooz reactor core in France. Data taking of the near detector has been started since 2015. We succeeded to take about 15 months of data for analysis as scheduled. Thanks to enhancement of computing and storage resources, we completed data processing, evaluation of detector performances and understandings of background events. Then we obtained realistic expectation of sensitivity to search for the sterile neutrino with statistics and systematics we have. This achievement was presented in some international conferences like ICHEP hold in August 2016. Submission to journal is expected soon after completion of real data analysis.
