Hadron production experiments

The HARP and NA61/SHINE hadroproduction experiments as well as their implications for neutrino physics are discussed. HARP measurements have already been used for predictions of neutrino beams in K2K and Mini-BooNE/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. 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 T2K experiment. Both HARP and NA61/SHINE experiments provide also a large amount of input for validation and tuning of hadron production models in Monte-Carlo generators.

Results from hadroproduction experiments

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.

Results from HARP and their implications for neutrino physics

Recent results from the HARP experiment on the measurements of the double-differential production cross-section of pions in proton interactions with beryllium, carbon and tantalum targets are presented. These results are relevant for a detailed understanding of neutrino flux in accelerator neutrino experiments MiniBooNE/SciBooNE, for a better prediction of atmospheric neutrino fluxes as well as for an optimization of a future neutrino factory design.
