Results and status from the HARP and MIPP hadron production experiments

Recent results and status from the HARP and MIPP hadron production experiments are reviewed. After a brief description of the experimental setups and the large amounts of data collected with those, we emphasize the relevance of precision hadron production measurements for neutrino physics. Three types of neutrino sources are discussed: conventional accelerator-based neutrino beams, advanced neutrino sources, and atmospheric neutrinos. We conclude by discussing prospects from additional hadron production measurements to be expected in the near future.
