| Outline of Final Research Achievements |
Having an aim to verify the existence of sterile neutrinos, which do not fit in the framework of the standard 3-flavor neutrino mixing, we have started a new experiment with an emulsion-based detector at J-PARC. The first step is detailed studies of low-energy neutrino-nucleus interactions. As a result of several test beam experiments, we have successfully detected a thousand events of antineutrino-nucleus interaction candidates with high multiplicity and have started studying them in detail. For the development of emulsion spectrometers, some prototypes have been produced by using lucite plates as good-planarity base material and Rohacell plates as low density spacer between emulsion films.
