The collision centrality dependences of the mean multiplicities and kinematical characteristics of negative pions produced in п−+12C collisions at 40 GeV/с are investigated. It is obtained that the average values of the partial inelasticity coefficients of negative pions (without “leading” pions) do not depend on the п−+12C collision centrality. It is shown that the normalized transverse momentum distributions, as well as the average values of the transverse momentum of negative pions, do not depend within the uncertainties on the п−+12C collision centrality. The average value of the emission angle of the negative pions was found to increase with the п−+12C collision centrality. The comparison of the normalized emission angle distributions of the negative pions in the peripheral and central п−+12C collisions at 40 GeV/с supported the assumption that such an increase in the average emission angle is likely due to an increase in the number of binary collisions and multiple rescatterings with the п−+12C collision centrality. The obtained experimental findings are reproduced qualitatively well by the Modified FRITIOF model calculations.

Collision centrality dependences of the transverse momentum distributions of negative pions produced in p12C and p−12C collisions at 9.9 and 40 GeV/c, respectively, are investigated. The shapes and widths of the normalized transverse momentum distributions, as well as the average values of the transverse momentum of the negative pions, do not depend within the uncertainties on the collision centrality in p12C and п−12C collisions at 9.9 and 40 GeV/c in experiment, which is confirmed by the modified FRITIOF model calculations and minimum X2 fits of the experimental spectra with the two- and three-temperature Hagedorn model functions. Modified FRITIOF model calculations underestimate the average values of transverse momenta of the negative pions in experiment and do not reproduce the tail of the experimental transverse momentum distributions of the negative pions in both collision types. It is obtained that the transverse momentum distributions of the negative pions exhibit two temperature (two-slope) shapes in peripheral and central p12C collisions at 9.9 GeV/c in agreement with the early works on nucleus-nucleus collisions at incident energies of the order of a few GeV/c. However, the transverse momentum distributions of the negative pions in peripheral and central p−12C collisions at 40 GeV/c can be described well assuming the three temperature (three-slope) shapes of these spectra.

Phenomenological Monte Carlo model of peripheral interactions of 9Be nuclei with emulsion nuclei at [Formula: see text][Formula: see text]GeV with formation of an excited 9Be* nucleus and its subsequent breakup, either directly or through formation of an intermediate 8Be nucleus, into two [Formula: see text]-particles and a neutron was constructed. A comparative analysis of the experimental data on angular correlations and momentum spectra of [Formula: see text]-particles, coming from a breakup event, with the Monte Carlo model calculations was made. The constructed Monte Carlo model described quite satisfactory the total momentum and transverse momentum distributions of [Formula: see text]-particles and the distribution of angles between the total momentum (as well as transverse momentum) vectors of two [Formula: see text]-particles in 9Be* nucleus breakup events in experiment. For the first time, the total momentum and transverse momentum distributions of neutrons, accompanying two [Formula: see text]-particles from 9Be* decay, in peripheral interactions of 9Be nuclei with emulsion nuclei were reconstructed using the Monte Carlo model.

The dependences of the shapes of transverse momentum distributions of the negative pions, produced in minimum bias 4 He +12 C collisions at a momentum of 4.2 GeV/c per nucleon, on collision centrality and fitting range of pt were analyzed systematically. To study the change in slopes (temperatures) of the pt spectra of π- with changing collision centrality and fitting pt range, the pt spectra, extracted from the experimental data and quark–gluon string model (QGSM) calculations, were fitted by the one- and two-temperature Hagedorn and Boltzmann functions. Fitting of the experimental pt distributions of π- in both the whole pt and pt = 0.1–1.2 GeV/c intervals required the two-temperature functions for adequate description of spectra, in agreement with the previous findings for different sets of colliding nuclei and various energies. On the whole, the absolute values of the extracted temperatures were lower in case of fitting range pt = 0.1–0.7 GeV/c as compared to the fitting interval pt = 0.1–1.2 GeV/c. The one-temperature functions were sufficient for fitting satisfactorily the experimental pt distributions of the negative pions in range pt = 0.1–0.7 GeV/c. In contrast to the experimental temperatures, the extracted QGSM temperatures were not sensitive to collision centrality and fitting range of pt. The collision centrality dependences of the temperatures of soft (pt = 0.1–0.5 GeV/c) and hard (pt = 0.5–1.2 GeV/c) components of the experimental pt distributions of the negative pions in 4 He +12 C collisions at 4.2A GeV/c were studied separately. The extracted temperatures of both soft and hard components of pt distributions of π- depended on geometry (size) and degree of overlap of colliding nuclei in peripheral, semicentral and central 4 He +12 C collisions. The temperature of soft pt component of the negative pions was consistently larger in semicentral and central 4 He +12 C collisions than that in peripheral interactions. The temperature of hard pt component of π- in 4 He +12 C collisions decreased consistently with an increase in collision centrality. The physical interpretations of the observed centrality dependences of temperature (T) of soft and hard pt components of the negative pions in 4 He +12 C collisions were given.

The midrapidity transverse momentum spectra of hadrons (p, K+, Ks0, ϕ, Λ, and (Ξ-+Ξ--)) and the available rapidity distributions of the strange hadrons (Ks0, (Λ+Λ-), (Ξ-+Ξ--)) produced in p-p collisions at LHC energy √sNN = 0.9 TeV have been studied using a Unified Statistical Thermal Freeze-out Model (USTFM). The calculated results are found to be in good agreement with the experimental data. The theoretical fits of the transverse momentum spectra using the model calculations provide the thermal freeze-out conditions in terms of the temperature and collective flow parameters for different hadronic species. The study reveals the presence of a significant collective flow and a well-defined temperature in the system thus indicating the formation of a thermally equilibrated hydrodynamic system in p-p collisions at LHC. Moreover, the fits to the available experimental rapidity distributions data of strange hadrons show the effect of almost complete transparency in p-p collisions at LHC. The model incorporates longitudinal as well as a transverse hydrodynamic flow. The contributions from heavier decay resonances have also been taken into account. We have also imposed the criteria of exact strangeness conservation in the system.

The average spectral temperatures of negative pions in 12 C 12 C collisions at 4.2A GeV/c were extracted from transverse momentum as well as scaled center-of-mass kinetic energy distributions for different intervals of rapidity and emission angle of π- in the center-of-mass system (cms) of 12 C 12 C collisions. The temperatures extracted from experimental spectra of negative pions were compared systematically with the corresponding temperatures deduced from spectra of π- calculated using Modified FRITIOF model. The dependence of the average spectral temperatures of negative pions on the rapidity and emission angle of π- in the cms of 12 C 12 C collisions at 4.2A GeV/c was analyzed.
