Results of analysis of experimental data on inclusive spectra of charged hadrons produced in heavy-ion collisions at RHIC are shown in z presentation. The data indicate similarity as a characteristic feature of mechanism of hadron production at high energies. It is argued that this property includes structure of the colliding objects, interaction of their constituents, and character of the fragmentation process. Relation of the scaling variable z with the entropy and "specific heat" of the interacting system is discussed. A microscopic scenario of the constituent interactions connected with the momentum distribution of hadrons in the final state is suggested. We estimate energy losses of particles in the produced matter characterized by the multiplicity density dN (ch)/d eta.

Výsledky analýzy experimentálních dat inklusivních spekter nabitých hadronů produkovaných ve srážkách těžkých iontů na RHIC jsou ukázány v z-presentaci. Data vykazují podobnost jako charakteristickou vlastnost mechanismu produkce hadronů při vysokých energiích.
