Neutrino Interaction research with Nuclear emulsion and J-PARC Accelerator : NINJA experiment

NINJA experiment aims to study Sub-Multi GeV neutrino-nucleus interactions and the exploration of a sterile neutrino using an Emulsion Cloud Chamber as the main detector at J-PARC neutrino beamline.
Currently, we are analyzing neutrino-water interactions taken in our first physics run (J-PARC E71a) which was implemented in 2019-2020 for the measurements of multi-nucleon reaction in neutrino interaction and reducing systematic uncertainties in current and future long-baseline neutrino oscillation experiments. NINJA aims to measure electron-neutrino interactions as well as muon-neutrino interactions. In this poster, the analysis status for the measurement of electron-neutrino interactions in NINJA will be shown, and discussed the future plans of the NINJA experiment.
