Phys. Rev. C 75, 054912 (2007) [6 pages]Specific heat in hadronic matter and in quark-gluon matterReceived 18 May 2006; revised 9 March 2007; published 25 May 2007 A parton and hadron cascade model, PACIAE, is applied to follow the particle transport in partonic and the hadronic stages in 0–5% most central Au+Au collisions at energies from SPS to RHIC. We have determined the specific heat of hadron matter (π++π-) in the hadronic final state and the specific heat of quark-gluon matter (u+d+g) in the partonic initial state in Au+Au collisions as a function of the reaction energy (excitation function). It turns out that the quark-gluon matter (QGM) specific heat is hard to survive the hadronization and there is not a peak structure in the specific heat excitation functions in studied energy region. © 2007 The American Physical Society URL:
