| Popis: | Simulation of meson–proton interactions is considered in the framework of a new phenomenological model (FANSY 2.0 QGSJ) developed on the basis of the traditional quark-gluon string model to simulate hadron interactions in a wide energy range. The model reproduces low-energy accelerator data on the generation of $$\pi ^0$$ mesons, $$\rho ^{+,0}$$ , $$\omega $$ and $$f_2$$ resonances, strange $$K^{*0,+}$$ , $$\bar{K}^{*0}$$ , $${K}^{*0}_2$$ and $$\phi $$ resonances, charmed $$D^{\pm ,0}$$ , $$D^{\pm }_s$$ and $$\bar{D}^0$$ mesons, p, $$\bar{p}$$ and $$\Delta ^{++}$$ baryons, $$\Lambda $$ and $$\bar{\Lambda }$$ hyperons in pion–proton and kaon–proton interactions. The relationship between the quark composition of the most energetic hadrons and the leading effect is discussed. A general agreement between simulated results and experimental data is shown. |
