Abstract: The chemical freeze-out irregularities found with the most advancedhadron resonance gas model and possible signals of two QCD phase transitionsare discussed. We found that the center-of-mass collision energy range of tri-critical endpoint of QCD phase diagram is [9; 9.2] GeV which is consistent bothwith QCD inspired exactly solvable model and with experimental findings.
