“…Neutrino Interaction research with Nuclear emulsion and J-PARC Accelerator (NINJA) is an experiment aiming to measure neutrino-nucleus, especially neutrino-water, interactions using a high-intensity neutrino beam produced in Japan Proton Accelerator Research Complex (J-PARC), and nuclear emulsion films. Since 2014, the NINJA experiment has carried out a series of pilot runs [5,6,7]. Nuclear emulsion films have sub-µm position resolution and O(mrad) angle resolution thanks to their fine granularity.…”

“…A series of neutrino-nucleus interaction measurements were conducted as part of the NINJA experiment [14][15][16] using an emulsion detector in the near detector hall of the T2K experiment at J-PARC. The aim was to precisely measure charged particles from neutrino interactions in the 1 GeV energy region.…”

“…The emulsion detector is suitable for the precise measurement of charged particles with a low momentum threshold owing to its thin-layered structure. Previous studies have reported the detector performance of the 2 kg iron pilot measurement [14] and the results of the 3 kg water pilot measurement [15]. Further, the measurement of the flux-averaged cross-sections and muon kinematics of the ν µ CC interaction of the 65 kg iron pilot measurement [16] have also been reported.…”

This study conducted an analysis of muons, protons, and charged pions emitted from νµ charged-current interactions on iron using a nuclear emulsion detector. The emulsion detector with a 65 kg iron target was exposed to a neutrino beam corresponding to 4.0×10 19 protons on target with a mean neutrino energy of 1.49 GeV. The measurements were performed at a momentum threshold of 200 (50) MeV/c for protons (pions), which are the lowest momentum thresholds attempted up to now. The measured quantities are the multiplicities, emission angles, and momenta of the muons, protons, and charged pions. In addition to these inclusive measurements, exclusive measurements such as the muon-proton emission-angle correlations of specific channels and the opening angle between the protons of CC0π2p events were performed. The data were compared to Monte Carlo (MC) predictions and some significant differences were observed. The results of the study demonstrate the capability of detailed measurements of neutrino-nucleus interactions using a nuclear emulsion detector to improve neutrino interaction models.

This paper reports the track multiplicity and kinematics of muons, charged pions, and protons from charged-current inclusiveν μ and ν μ interactions on a water target, measured using a nuclear emulsion detector in the NINJA experiment. A 3-kg water target was exposed to the T2K antineutrino-enhanced beam corresponding to 7.1 × 10 20 protons on target with a mean energy of 1.3 GeV. Owing to the high granularity of the nuclear emulsion, protons with momenta down to 200 MeV=c from the neutrino-water interactions were detected. We find good agreement between the observed data and model predictions for all kinematic distributions other than the number of charged pions and the muon kinematics shapes. These results demonstrate the capability of measurements with nuclear emulsion to improve neutrino interaction models.
