We use a kinetic condition to predict the chemical freeze-out parameters for hadronic species produced in heavy ion collisions. The resulting freeze-out lines for different hadrons lie close to one another in the temperature and baryochemical potential plane, defining a universal, narrow region. The chemical freeze-out is driven by the localization of hadrons due to the chiral symmetry breaking and confining aspects of the QCD transition.

Within a generalized Beth-Uhlenbeck cluster model, the paper concludes that chemical freeze-out of hadrons coincides with their Mott dissociation at the chiral crossover temperature.
