First neutrino event detection with nuclear emulsion at J-PARC neutrino beamline
First neutrino event detection with nuclear emulsion at J-PARC neutrino beamline
Precise neutrino--nucleus interaction measurements in the sub-multi GeV region are important to reduce the systematic uncertainty in future neutrino oscillation experiments. Furthermore, the excess of ${\nu_e}$ interactions, as a possible interpretation of the existence of a sterile neutrino has been observed in such an energy region. The nuclear emulsion technique …
