Hadron yields, the chemical freeze-out and the QCD phase diagram

Abstract

We present the status of the chemical freeze-out, determined from fits of hadron yields with the statistical hadronization (thermal) model, with focus on the data at the LHC. A description of the yields of hadrons containing light quarks as well as the application of the model for the production of the J/$\psi$ meson is presented. The implications for the QCD phase diagram are discussed.
