Description
For atmospheric and long-baseline neutrino oscillation experiments, as well as astro-neutrino-like supernova neutrinos, understanding hadron reactions is essential for neutrino generation. Neutrinos are produced by striking a nucleus such as carbon, nitrogen or oxygen with a primary proton, and then the emitted hadrons, such as pions and kaons, decay in flight providing neutrinos. The hadron interaction is a primary source of the atmospheric and beam neutrino flux prediction uncertainty. Therefore, accurate hadron production and hadron-nucleus interaction measurements are critical. This is one of the objectives of the NA61/SHINE experiment at the Super Proton Synchrotron at CERN. In this presentation, the results of the neutrino program 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/SHINE’s physics program in the near future. The low-energy hadron production measurements will be beneficial for not only neutrino oscillation experiments but also supernova neutrino observations because atmospheric neutrinos are one of serious backgrounds.
