Abstract

The statistical bootstrap model is critically revised in order to include a medium-dependent resonance width in it. We show that a thermodynamic model with a vanishing width below the Hagedorn temperature TH and a Hagedorn spectrum-like width above TH may not only eliminate the divergence of the thermodynamic functions above TH, but also gives a satisfactory description of the lattice quantum chromodynamics data on the energy density above the chiral/deconfinement transition as the main result of this contribution. This model allows us to explain the absence of heavy resonance contributions in the fit of the experimentally measured particle ratios at SPS and RHIC energies.
