More uses for thermal models

We explore combinations of particle and anti-particle yields which can be used to test thermal models in a parameter free way. We also explore combinations which can be used to extract μ B/T μ B / T , μ S/T μ S / T and μ Q/T μ Q / T . We use experimentally measured particle-antiparticle specific ratios for proton p , Lambda Λ Λ , and cascade Ξ Ξ , for √sNN= s NN = 7.7–39 GeV from RHIC BES phase-1 to extract the μ B,S,Q/T μ B , S , Q / T . These compared well with published STAR freeze-out parameters. These combinations are verified to predict a similar combination of Ω Ω yields. We also extend this idea to predict (anti-)nuclei yields at energies where they are not measured. We also update parametrizations for the √sNN s NN dependence of freeze-out parameters T and μ B μ B , and present for the first time a similar parametrization of μ S μ S .
