Abstract

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 $K^{\ast 0,+}$, ${\overline{K}}^{\ast 0}$, $K_2^{\ast 0}$ and $\varphi$ resonances, charmed $D^{\pm ,0}$, $D_s^{\pm }$ and ${\overline{D}}^0$ mesons, p, $\overline{p}$ and ${\mathrm{\Delta }}^{++}$ baryons, $\mathrm{\Lambda }$ and $\overline{\mathrm{\Lambda }}$ 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.
