摘要：

The Hagedorn temperature, T-H is determined from the number of hadronic resonances including all mesons and barons. This leads to a stable result T-H = 174 MeV consistent with the critical and the chemical freeze-out temperatures at zero chemical potential. We use this result to calculate the speed of sound and other thermodynamic quantities in the resonance hadron gas model for a wide range of baryon chemical potentials following the chemical freeze-out curve. We compare some of our results to those obtained previously in other papers.
