The results of this dynamical approach is analyzed in comparison with the model of statistical (multi)fragmentation, namely, the cascade model including evaporation and multifragmentation, developed in the framework of percolation model.

In this paper, the current status of simulations of electronÄpositron pair measurements in MPD is presented and the detector performance for such measurements is discussed. ¤´μ°¨ § μ¸´μ¢´ÒÌ § ¤ Î ¢ ˨ §¨Î¥¸±μ° ¶•μ£• ³³¥ Ô±¸ ¶¥•¨³¥´É MPD´ ±μ³ ¶²¥±¸¥ NICA Ö¢²Ö¥É¸Ö¨ §ÊÎ¥´¨¥ ¢¥±Éμ•´ÒÌ ³¥ §μ´μ¢¸³ ²μ°³ ¸¸μ°ρ, ω, φ¸¨¸ ¶μ²Ó §μ¢ ´¨¥³¨Ì ²¥ ¶Éμ´´μ°³ μ¤Ò • ¸ ¶ ¤. ‚ • ¡μÉ¥ ¶•¥¤¸É ¢²¥´¸É Éʸ³μ¤¥²¨•μ¢ ´¨Ö¨ §³¥•¥´¨°Ô²¥±É•μ´-¶μ §¨É•μ´´ÒÌ ¶ • ¢ MPD¨μ¡¸Ê¦¤ ÕÉ¸Ö ¢μ §³μ¦´μ¸É¨¤¥É¥±Éμ• ¤²Ö Ôɨ̨ §³¥•¥´¨°.

The absolute cross-sections of the residual nuclei were compared with the theoretical ones calculated by the standard cascade-evaporation and the intranuclear cascad plus statistical multifragmentation models (INC + SMM). It was shown that at E p = 8.1 GeV these nuclei may arise both from disintegration of the nucleus and as partners of several fragments.

Applying the model to larger collections of nucleons reveals the emergence of the face-centered cubic (FCC) symmetry at the nuclear level. Nuclei with closed shells possess octahedral symmetry. Binding of nucleons are provided by quark loops formed by three and four nucleon correlations. Quark loops are responsible for formation of exotic (borromean) nuclei, as well. The model unifies independent particle (shell) model, liquid-drop and cluster models.

These in-medium modifications can lead to observable effects in heavy ion collisions, such as enhancement of strangeness and dropping vector meson masses.

We argue that the data indicate the transition of the nucleons in the overlap region of colliding nuclei with high nuclear density into a certain hyperon phase. This nucleon-to-hyperon transition is accompanied by enhanced yields of positive kaons. The "horn"-effect is a consequence of an interplay between the energy/baryon density attained in the overlap region of colliding nuclei and the overlap time.

Connection of the model considerations with Casimir effect is discussed.

It is shown that dominating factors of appearance of SSA are the orbiting around the valence quarks sea quark and qluon condensates and spin dependent quark‐quark cross sections. © 2007 American Institute of Physics

Applying the model to larger collections of nucleons reveals the emergence of symmetries at the nuclear level that are implied by the quark-quark interaction specifically, geometrical shells and subshells that are isomorphic with those known from the independent-particle (shell) model (Fig. 1). This discrete nuclear symmetry discovered by Cook with coauthors corresponds to face-centered-cubic lattice [3].

Quarks were first postulated as constituents of hadrons with masses about hundreds of MeV to describe the spectroscopy of hadrons. Subsequently, it was realized that hard processes are the arena of current quark considerations with masses much lighter than the original constituent ones. Relationship between current and constituent quarks is still smooth and unclear. According to the modern picture of hadrons quark-antiquark in mesons and three valence quarks in nucleons are dressed with gluons and ”sea” quark-antiquark pairs in such a way that they become much heavier, although the dynamical mechanism of dressing is not understood definitely.
