Interaction cross sections and charged pion spectra in p + C interactions at 31 GeV/c were measured with the large-acceptance NA61/SHINE spectrometer at the CERN SPS. These data are required to improve predictions of the neutrino flux for the T2K long-baseline neutrino oscillation experiment in Japan. A set of data collected during the first NA61/SHINE run in 2007 with an isotropic graphite target with a thickness of 4% of a nuclear interaction length was used for the analysis. The measured p + C inelastic and production cross sections are 257.2 ± 1.9 ± 8.9 and 229.3 ± 1.9 ± 9.0 mb, respectively. Inclusive production cross sections for negatively and positively charged pions are presented as functions of laboratory momentum in ten intervals of the laboratory polar angle covering the range from 0 up to 420 mrad. The spectra are compared with predictions of several hadron production models.

Parametrization of the nucleus-nucleus γ -ray production cross sections below 100 GeV/nucleon: Subthreshold pions and hard photons

"Subthreshold pions" and so-called "hard photons" are two important channels for producing less than 1 GeV γ-rays and e ± pairs from nuclear collisions with energy per nucleon below the π-meson production threshold. I use publicly available experimental data to parametrize these two channels' γ-ray and e ± production cross sections and extend the pion contribution to these particles spectra at higher energies using their corresponding spectra from pp interactions. These parametrizations are valid for collision energy Tp ≤ 100 A GeV and agree reasonably well with the available experimental data. The new parametrizations allow, for the first time, accurate studies of astrophysical γ-rays below 1 GeV.

Extension of the Liège intranuclear cascade model at incident energies between 2 and 12 GeV. Aspects of pion production

The validity of the standard version of the Liège Intra-Nuclear Cascade (INCL4) model, which has been shown to be quite successful for the description of spallation reactions, is limited to an upper incident energy of ∼2 GeV, because inelastic elementary processes are restricted to the excitation and de-excitation of the Delta resonance. In this paper, the INCL4 model is extended to higher incident energy by including other inelastic elementary collisions. However, excitation of heavier baryonic resonances is replaced by direct multipion production in elementary nucleon-nucleon and pion-nucleon collisions. The predictions of the modified model for production of charged pions by proton and pion beams off nuclei are compared with experimental data of the HARP Collaboration for beam energies between 2 and 12 GeV. The apparent duality between the approach based on excitation of numerous baryonic resonances and our approach is briefly discussed.
