We present the status of the description of hadron production in central nucleus-nucleus collisions within the statistical model . The recent inclusion of very high-mass resonances and the sigma meson leads to an improved description of the data, in particular the energy dependence of the K+/pi+ ratio at SPS energies (``the horn''). The connection to the QCD phase diagram is discussed.

    hep-ph 2026-02 unverdicted novelty 5.0

    Combinations of particle yields enable parameter-free tests of thermal models and extraction of μ_B/T, μ_S/T, μ_Q/T from RHIC BES data, matching published parameters and allowing predictions for other particles and nuclei.
