Production of charged pions by 730-MeV protons from hydrogen and selected nuclei

Cochran, D.R.F. ; Dean, P.N. ; Gram, P.A.M. ; et al.
Phys.Rev.D 6 (1972) 3085-3116, 1972.
Inspire Record 73637 DOI 10.17182/hepdata.22253

An experiment was done in the external proton beam of the Berkeley 184-in. cyclotron to measure the production cross sections for pions from various target nuclei, from hydrogen to lead. The cross-section data are presented and the reaction mechanisms discussed. The hydrogen production appears to fit the one-pion-exchange model.

Excitation of the Delta (1232) resonance in proton - nucleus collisions

Trzaska, M. ; Pelte, D. ; Lemaire, M. -C. ; et al.
Z.Phys.A 340 (1991) 325-331, 1991.
Inspire Record 314551 DOI 10.17182/hepdata.15689

The excitation of theΔ resonance is observed in proton collisions on C, Nb and Pb targets at 0.8 and 1.6 GeV incident energies. The mass E0 and widthΓ of the resonance are determined from the invariant mass spectra of correlated (p, π±)-pairs in the final state of the collision: The mass E0 is smaller than that of the free resonance, however by comparing to intra-nuclear cascade calculations, this reduction is traced back to the effects of Fermi motion, NN scattering and pion reabsorption in nuclear matter.

Measurements of Cross Sections and Charged Pion Spectra in Proton-Carbon Interactions at 31 GeV/c

The NA61/SHINE collaboration Abgrall, N ; Aduszkiewicz, A ; Andrieu, B ; et al.
Phys.Rev.C 84 (2011) 034604, 2011.
Inspire Record 886780 DOI 10.17182/hepdata.57596

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 mb and 229.3 +- 1.9 +- 9.0 mb, respectively. Inclusive production cross sections for negatively and positively charged pions are presented as a function of laboratory momentum in 10 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.
