Description
In current measurements of neutrino properties with accelerator-based neutrino experiments, neutrino flux uncertainties represent a leading systematic uncertainty. Neutrino beams are created from the decays of hadrons produced in hadron-nucleus interactions. Primary and secondary hadron production processes are the leading source of the flux uncertainty. To constrain the neutrino flux uncertainty arising from hadron production, external hadron production data are crucial. The neutrino program of the NA61/SHINE experiment at CERN's Super Proton Synchrotron conducts a series of dedicated measurements for this purpose.
In this talk, we will first present recent hadron production measurements used for the precise determination of neutrino flux needed by T2K and the Fermilab long-baseline neutrino experiments. We will then review the recent data collection status with the upgraded NA61/SHINE facility. Lastly, we will discuss the prospect for future measurements including the possibility of a low-energy beamline to extend the physics program for accelerator-based and non-accelerator neutrino experiments.
