Erice: INTERNATIONAL SCHOOL OF NUCLEAR PHYSICS, 47th COURSE

A key requirement for realizing the full physics potential of current and future neutrino experiments – including T2K, NOvA, Hyper-Kamiokande, and DUNE with both accelerator-based and atmospheric neutrino measurements – is the reduction of uncertainties in neutrino flux predictions. A major source of these uncertainties comes from the limited understanding of primary and secondary hadron-nucleus interactions within the beamline or the atmosphere. With the goal of measuring these interactions in thin and replica targets, a dedicated program was developed at the NA61/SHINE experiment at CERN. This contribution will present the plans and results for concurrent analyses on the hadron production measurements conducted at NA61/SHINE using thin and replica targets for T2K, the NuMI experiments, and DUNE.
