Measurement of particle production in proton induced reactions at 14.6-GeV/c

The E-802 collaboration Abbott, T. ; Akiba, Y. ; Beavis, D. ; et al.

Particle production in proton-induced reactions at 14.6 GeV/c on Be, Al, Cu, and Au targets has been systematically studied using the E-802 spectrometer at the BNL-Alternating Gradient Synchrotron. Particles are measured in the angular range from 5° to 58° and identified up to momenta of 5, 3.5, and 8 GeV/c for pions, kaons, and protons, respectively. Mechanisms for particle production are discussed in comparison with heavy-ion-induced reactions at the same incident energy per nucleon.

Cross-sections of large-angle hadron production in proton- and pion-nucleus interactions IV: Copper nuclei and beam momenta from +/-3 GeV/c to +/-15 GeV/c

The HARP-CDP collaboration Bolshakova, A. ; Boyko, I. ; Chelkov, G. ; et al.
Eur.Phys.J.C 64 (2009) 181-241, 2009.
Inspire Record 823636 DOI 10.17182/hepdata.52601

We report on double-differential inclusive cross-sections of the production of secondary protons, charged pions, and deuterons, in the interactions with a 5% nuclear interaction length thick stationary copper target, of proton and pion beams with momentum from +/-3 GeV/c to +/-15 GeV/c. Results are given for secondary particles with production angles between 20 and 125 degrees.

High-energy proton scattering on nuclei

Klovning, A. ; Kofoed-Hansen, O. ; Schluepmann, K. ;
Nucl.Phys.B 54 (1973) 29-41, 1973.
Inspire Record 84178 DOI 10.17182/hepdata.32651

We have studied high-energy proton scattering on Be, C, Cu and Pb targets using a single-arm spectrometer. The projectile momenta were 19 and 24 GeV/ c , the square of the four-momentum transfer varied from t = 0.1 to t = 4.4 GeV 2 . We have recorded momentum distributions of scattered protons in the high-momentum range. An application of multiple-scattering theory yielded agreement of calculation and experimental results to within a ± 30% uncertainty of the former.

PARTICLE PRODUCTION IN THE TARGET RAPIDITY REGION FROM HADRON NUCLEUS REACTIONS AT SEVERAL GEV

Shibata, T.A. ; Nakai, K. ; Enyo, H. ; et al.
Nucl.Phys.A 408 (1983) 525-558, 1983.
Inspire Record 197272 DOI 10.17182/hepdata.8739

Highly inelastic processes in hadron-nucleus reactions at several GeV have been studied by measuring multi-particle emission in the target-rapidity region. Events with no leading particle(s) but with high multiplicities were observed up to 4 GeV. Proton spectra from such events were well reproduced with a single-moving-source model, which implied possible formation of a local source. The number of nucleons involved in the source was estimated to be (3–5)A 1 3 from the source velocity and the multiplicity of emitted protons. In those processes the incident energy flux seemed to be deposited totally or mostly (>62;75%) in the target nucleus to form the local source. The cross sections for the process were about 30% of the geometrical cross sections, with little dependence on incident energies up to 4 GeV and no dependence on projectiles (pions or protons). The E 0 parameter in the invariant-cross-section formula E d 3 σ /d p 3 = A exp (− E / E 0 ) for protons from the source increases with incident energy from 1 to 4 GeV/ c , but seems to saturate above 10 GeV at a value E 0 = 60–70 MeV. Three components in the emitted nucleon spectra were observed which would correspond to three stages of the reaction process: primary, pre-equilibrium and equilibrium.
