Abstract content

Nuclear emulsion is a 3D tracking detector with sub-micron resolution. Thanks to its high spatial resolution, emulsion can detect short-length tracks and measure neutrino interactions with a low energy threshold, especially multi-nucleon interactions. Furthermore, emulsion has 4 ¥pi tracking acceptance and provides flexibility in the choice of target materials, even water may be used. Emulsion is therefore suitable for the precise measurement of neutrino and hadron interactions to reduce the systematic uncertainties from neutrino cross-section and flux in current and future oscillation experiments, with the aim of observing ¥nu CP violation. We have been carrying out two hybrid emulsion experiments, NINJA and EMPHATIC, which aim to measure sub-multi GeV neutrino cross-sections at J-PARC and hadron cross-sections from a few to 120 GeV at Fermilab respectively. In this poster, we present the latest developments in emulsion technology and the status/future prospects of NINJA and EMPHATIC.
