Description
In long-baseline neutrino oscillation experiments, understanding hadron reactions is essential for neutrino generation. Neutrinos are produced by striking a carbon target with proton beam and then decaying the emitted hadrons such as pions and kaons. The hadron interaction is a primary source of the neutrino beam flux prediction uncertainty. Therefore, accurate hadron production and hadron-nucleus interaction measurements are critical. The NA61/SHINE experiment at the Super Proton Synchrotron at CERN is being conducted with that as one of its objectives. In this presentation, the results of the neutrino program so far are reviewed. Next, the recent measurements for T2K and Fermilab long-baseline neutrino experiments are presented. Finally, we discuss the prospects for future hadron production measurements including a low-energy beamline that may extend NA61/SHINEʼs physics program in the near future. The low-energy hadron production measurements will be beneficial for not only long-baseline neutrino oscillation but also atmospheric neutrino oscillation experiments.
