| Abstract: | 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 S / T and μ Q / T . We use experimentally measured particle-antiparticle specific ratios for proton p, Lambda Λ , and cascade Ξ , for s NN = 7.7–39 GeV from RHIC BES phase-1 to extract the 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 yields. We also extend this idea to predict (anti-)nuclei yields at energies where they are not measured. We also update parametrizations for the s NN dependence of freeze-out parameters T and μ B , and present for the first time a similar parametrization of μ S . [ABSTRACT FROM AUTHOR] |
