Popis: | We discuss, in qualitative and quantitative fashion, the yields of hadron resonances. We show that these yields, in general, are not in chemical equilibrium. We evaluate the non-equilibrium abundances in a dynamic model implementing the $1+2\leftrightarrow 3$ resonance formation reactions. Due to the strength of these reactions, we show the $\Sigma(1385)$ enhancement, and the $\Lambda(1520)$ suppression explicitly.
