FANSY 2.0: a Monte Carlo tool for study of superhigh-energy cosmic-ray interactions: meson-proton interactions

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 f2 resonances, strange K0,+, K0, K20 and phi resonances, charmed D +/- ,0, Ds +/- and D0 mesons, p, p and Delta ++ baryons, Lambda and 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.

A new phenomenological model (FANSY 2.0 QGSJ) based on the traditional quark-gluon string model has been developed to simulate meson-proton interactions in a wide energy range. The model successfully reproduces low-energy accelerator data and shows a general agreement between simulated results and experimental data. The relationship between the quark composition of the most energetic hadrons and the leading effect is discussed.
