For this purpose, three reactions have been selected: Au+Au at 1 and 1.48 A GeV and Ni+Ni at 1.93 A GeV. Public work category ADC No. of Archival Copy 26409 Catal.org.

The regular part of the polarization operator is extracted from the realistic kaon-nucleon interaction based on the chiral and 1/N-c expansion. Contributions of Lambda(1116), Sigma(1195), Sigma*(1385) resonances are taken explicitly into account in the pole and regular terms with the inclusion of mean-field potentials. The baryon-baryon correlations are incorporated and fluctuation contributions are estimated. Results are applied for K- in neutron star matter. Within our model a second-order phase transition to the s-wave K- condensate state occurs at rho(c)greater than or similar to4rho(0) with baryon-baryon correlations included. We show that a second-order phase transition to the p-wave K- condensate state may occur at densities rho(c)similar to(3-5)rho(0) dependent on the parameter choice. We demonstrate that a first-order phase transition to a proton-enriched (approximately isospin-symmetric) nucleon matter with a p-wave K- condensate can occur at smaller densities, rholess than or similar to2rho(0). The transition is accompanied by the suppression of hyperon concentrations.

Source document Physics of Atomic Nuclei. Vol. 56, no. 2 (1993), pp. 252-259. - New York : Pleiades Publishing, 1993 Keywords Pion-production nucleus-nucleus collisions Form. Descr. články - journal articles Language English Country United States of America Annotation Various processes of pion production in nuclear matter at characteristic temperatures T much less than m(pi) are analyzed. It is shown that the pions are produced mainly in NN --> NN(pi) reactions. Taking into account the modification of the NN interaction in nucelar matter, probabilities and differential cross sections of production of pi- mesons in direct NN --> NNpi- reactions are calculated. It is shown that at incident-pion momenta q approximately 2m(pi) processes with pion production via DELTA-resonance intermediate states dominate. From a comparison of the results of the calculation with experimental data on pion production in nucleus-nucleus collisions it is concluded that piN absorption is strong and increases with increasing temperature and density of the nuclear matter. At the initial stage of development of the nuclear fireball the pions are confined inside the system at practically all momenta. Soft (q less-than-or-similar-to m(pi)) pions are emitted at the intermediate stage of expansion of the nuclear fireball, and harder pions are released together with nucleons at the final stage of breakup of the fireball.
