A number of models of high-energy hadron-nucleus interactions are used in cosmic-ray experiments, however none of them can explain the entire experimental data set of EAS features. Besides, a number of phenomena observed in mountain-based and stratospheric X-ray emulsion chamber cosmic-ray experiments are not explained yet, for example, the so-called coplanarity of EAS’s most energetic subcores. A new phenomenological model FANSY 2.0 is designed to simulate hadron interactions at superhigh energies and reproduces results of cosmic-ray experiments and accelerator and collider data. FANSY 2.0 reproduces ALICE, ATLAS, CMS, TOTEM data on particle generation in the central kinematic region, LHCf data on high-x F gamma-rays and neutrons, as well as low-energy data on stable, charmed and resonance particle generation. The traditional quark-gluon string model-based version, FANSY 2.0 QGSJ, is considered. Simulated results are compared with experimental data.
