Coupling dynamical and statistical mechanisms for baryonic cluster production in nucleus collisions of intermediate and high energies

چکیده

Central nucleus-nucleus collisions produce many new baryons and the nuclear clusters can be formed from these species. The phenomenological coalescence models were sufficiently good for description of light nuclei yields in a very broad range collision energies. We demonstrate that reality process considered as 1) formation primary diluted excited baryon 2) their following statistical decay leading to final cold fragment production. argue such systems interacting is natural consequence interaction at subnuclear densities resulting liquid-gas type phase transition finite systems. In this way one provide consistent interpretation experimental (FOPI data) including important energy dependence relativistic ion reactions. investigate regularities kind production, example, yield, isospin, kinetic characteristics. A generalization clusterization mechanism hypernuclear matter suggested. isotope particle correlations should adequate studying phenomena.

Comparative Analysis of the Mechanisms of Fast Light Particle Formation in Nucleus-Nucleus Collisions at Low and Intermediate Energies

The dynamics and the mechanisms of preequilibrium-light-particle formation in nucleusnucleus collisions at low and intermediate energies are studied on the basis of a classical four-body model. The angular and energy distributions of light particles from such processes are calculated. It is found that, at energies below 50 MeV per nucleon, the hardest section of the energy spectrum is formed ow...

Asymptotic properties of high-pT particle production in hadron-hadron, hadron-nucleus and nucleus-nucleus collisions at high energies

The concept of z-scaling reflecting the general features of internal particle substructure, constituent interaction and mechanism of real particle formation is reviewed. Experimental data on the cross sections obtained at ISR, SpS and Tevatron are used in the analysis. The properties of data z-presentation, the energy and angular independencies, the power law, Aand F -dependencies, are discusse...

Two Pion Production in Nucleon-nucleon Collisions at Intermediate Energies

We have developed a model for the NN → NNππ reaction and evaluated cross sections for the different charged channels. The low energy part of those channels where the pions can be in an isospin zero state is dominated by N∗(1440) excitation, driven by an isoscalar source followed by the decay N∗ → N(ππ) S−wave . At higher energies, and in channels where the pions are not in T=0, ∆ excitation mec...
