Obtaining the specific heat of hadronic matter from CERN/RHIC experiments

The specific heat of hot hadronic matter is related to particle production yields from experiments done at CERN/RHIC. The mass fluctuation of excited hadrons plays an important role. Connections of the specific heat, mean hadronic mass excited and its fluctuation with properties of baryon and electric charge chemical potentials (value, slope and curvature) are also developed. A possible divergence of the specific heat as 1/(T0 – T)2 is discussed. Some connections with net charge fluctuations are noted.
