Measurements of the double-differential π ± production cross section in the range of momentum 100 p 800 MeV/c and angle 0.35 θ 2.15 rad using π ± beams incident on beryllium, aluminum, carbon, copper, tin, tantalum, and lead targets are presented. The data were taken with the large-acceptance hadron production (HARP) detector in the T9 beam line of the CERN Proton Synchrotron. The secondary pions were produced by beams in a momentum range from 3 to 12.9 GeV/c hitting a solid target with a thickness of 5% of a nuclear interaction length. The tracking and identification of the produced particles was performed using a small-radius cylindrical time projection chamber placed inside a solenoidal magnet. Incident particles were identified by an elaborate system of beam detectors. Results are obtained for the double-differential cross sections d 2 σ /dp dθ at six incident-beam momenta. Data at 3, 5, 8, and 12 GeV/c are available for all targets, while additional data at 8.9 and 12.9 GeV/c were taken in positive particle beams on Be and Al targets, respectively. The measurements are compared with several generators of GEANT4 and the MARS Monte Carlo simulation.

“…Track recognition, momentum determination and particle identification were all performed based on the measurements made with the TPC (see [21] for more details). Full spill data were analyzed and published for incoming protons [24] and pions [25], after the development of a special algorithm to correct for the TPC dynamic distortions [31] and validation of the TPC performance with benchmarks based on real data [32], An additional comparison was also performed on the pion yields measured with the short (5% λ I ) and long (100% λ I ) nuclear targets [33].…”

Abstract.Results from fixed-target hadroproduction experiments (HARP, MIPP, NA49 and NA61/SHINE) as well as their implications for cosmic ray and neutrino physics are reviewed. HARP measurements have been used for predictions of neutrino beams in K2K and MiniBooNE/SciBooNE experiments and are also being used to improve predictions of the muon yields in EAS and of the atmospheric neutrino fluxes as well as to help in the optimization of neutrino factory and super-beam designs. Recent measurements released by the NA61/SHINE experiment are of significant importance for a precise prediction of the J-PARC neutrino beam used for the T2K experiment and for interpretation of EAS data. These hadroproduction experiments provide also a large amount of input for validation and tuning of hadron production models in Monte-Carlo generators.

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.Comment: proceedings of the XXV International Conference on Neutrino Physics and Astrophysics, June 2012, Kyoto (Japan). arXiv admin note: substantial text overlap with arXiv:1106.438
