Description

Hadronization models are successfully describing the particle yields, particularly in high-energy nucleus-nucleus collisions [1]. They are also used to describe elementary processes, like pp interactions. Extensive measurements at $\sqrt{s}$= 17.3 GeV by NA49 and NA61/SHINE collaborations provided yields of numerous particles, including double-strange hyperons.
Reasonable description of all experimentally measured yields (including the enfant terrible of these models, the $\phi$ meson) was possible only when the canonical radius of volume containing strange particles was allowed to vary independently [2,3]. In this report, the extension of the hadronization model calculations within ThermalFist [4] using the new results obtained at lower energies by NA61/SHINE will be presented.
