Abstract

The hadroproduction experiments HARP, MIPP and NA61 (SHINE) as well as their implications for neutrino physics are discussed. HARP measurements have already been used for precise predictions of neutrino beams in K2K and MiniBooNE/SciBooNE experiments and are also being used to improve the atmospheric neutrino flux predictions and to help in the optimization of neutrino factory and super-beam designs. The MIPP experiment has nearly finalized measurements of hadron production from the NuMI target used in the MINOS experiment. First measurements released recently by the NA61 (SHINE) experiment are of significant importance for a precise prediction of the J-PARC neutrino beam used for the first stage of the T2K experiment. All three experiments - HARP, MIPP and NA61 - provide also a large amount of input for validation and tuning of hadron production models in Monte-Carlo generators.
