“…After introducing all of the above-mentioned corrections, we obtained the mean multiplicity per event of participant protons to be 1.94 ± 0.06 in the present analysis, with a statistics of 7071 inelastic d + 12 C events, measured under 4π acceptance, corresponding to the cross section 400 ± 20 mb. The mean multiplicity of participant protons calculated using the Dubna cascade model (DCM) [56,57], the FRITIOF model [58][59][60][61][62], and the quark-gluon-string model (QGSM) [63] were 1.97 ± 0.01 [52], 2.05 ± 0.03 [55], and 1.86 ± 0.02 [64], respectively.…”

Production of 0 (1232) resonances in d + 12 C collisions at 4.2A GeV/c was investigated with 4π acceptance, for the first time. The mass distribution of 0 (1232) resonances produced in d + 12 C collisions was reconstructed and their mass and width were extracted. The kinematical distributions of 0 (1232) were reconstructed in the laboratory frame and the corresponding mean kinematical characteristics were estimated. The fraction of charged π − mesons coming from 0 (1232) decay as well as the relative number of nucleons excited to 0 (1232) in freeze-out conditions were estimated. The freeze-out temperature of 0 (1232) was estimated and compared to results of other experiments with different sets of colliding nuclei and various incident energies.

“…Momenta of the nucleons ejected from a nucleus are sampled according to a Fermi motion algorithm. A simple model for estimating Reggeon cascading in hA and AA interactions was proposed by EMU01 collaboration ( [40] and references therein). When considering a Fermi motion of nucleons it was found that the two FRITIOF codes (with and without de-excitation) give similar results for p, 4 He, 12 C, 16 O, 22 Ne, and 32 S induced interactions with emulsion nuclei at 3.1 to 3.5A GeV [40].…”

The behavior of the relativistic hadron (shower particle) multiplicity for 32 S-nucleus interactions is investigated. The experiment is carried out at 3.7A GeV (Dubna energy) and 200A GeV (SPS energy) to search for the incident energy effect on the interactions inside the different emulsion target nuclei. Data are presented in terms of the number of emitted relativistic hadrons in both forward and backward angular zones. The dependence on the target size is presented. For this purpose the statistical events are separated into groups according to the interactions with H, CNO, Em, and AgBr target nuclei. The separation of events, into these groups, is executed based on predictions of Glauber's multiple scattering theory. Features suggestive of a decay mechanism seem to be a characteristic of the backward emission of relativistic hadrons. The results strongly support the assumption that the relativistic hadrons may already be emitted during the de-excitation of the excited target nucleus, in a behavior like that of compound nucleus disintegration. Regarding the limiting fragmentation hypothesis beyond 1 GeV, the target size is the main parameter affecting the backward production of relativistic hadrons. The backward shower particle multiplicity can indicate the impact parameter. The incident energy is a principle factor responsible for the forward relativistic hadron production, implying that this system of particle production is a creation system. However, the target size is an effective parameter as well as the projectile size considering the geometrical concept seen in the nuclear fireball model. The forward shower particle multiplicity distributions may behave in a similar trend at Dubna energy and SPS for low target sizes. For heavy target sizes, the SPS energy reveals the creation of hadrons with nearly equal probabilities over a wide range of multiplicity, extending to more than 300 hadrons per event. The data are analyzed in the framework of the FRITIOF model.

Application of the HIJING, EPOS 1.99, UrQMD and Geant4 FTF models for the analysis of experimental data by the collaboration is considered. A short description of the models is given. It is shown that the FTF (FRITIOF) model of the Geant4 toolkit describes well the NA61/SHINE data on $$\pi ^-$$ π - meson rapidity distributions in $${ ^{40}\mathrm{Ar}+{}^{45}\mathrm{Sc}}$$ 40 Ar + 45 Sc interactions at $$\sqrt{s_{NN}}=$$ s NN = 5.2 and 6.1 GeV. At higher energies, $$\sqrt{s_{NN}}=$$ s NN = 7.6, 8.8, 11.9 and 16.8 GeV, the model underestimates the data by 13%, 14%, 14% and 27%, respectively. The model also describes well the analogous data for $${^{7}\mathrm{Be}+{}^{9}\mathrm{Be}}$$ 7 Be + 9 Be interactions at all energies ($$\sqrt{s_{NN}}=$$ s NN = 6.1–16.8 GeV). It is the best model description among the descriptions of other models considered by the collaboration.
