Abstract content

Motivated by the importance of the measurement of p+C and pi+C interactions for tuning hadronic interaction models used in neutrino flux and extensive air shower simulations, we analyze pion production in p+C and pi+C reactions at 12GeV/c measured in the fixed target experiment HARP at CERN-PS. We present momentum spectra of positive and negative pions in the momentum range from 0.5GeV/c to 8.0GeV/c and angular range from 30mrad to 210mrad. The results are compared with predictions of frequently used hadronic interaction models and a Sanford-Wang parametrisation is fit to the data.
