High-precision thermodynamics and Hagedorn density of states
We compute the entropy density of the confined phase of QCD without quarks on the lattice to very high accuracy. The results are compared to the entropy density of free glueballs, where we include all the known glueball states below the two-particle threshold. We find that an excellent, parameter-...

| Summary: | We compute the entropy density of the confined phase of QCD without quarks on the lattice to very
high accuracy. The results are compared to the entropy density of free glueballs, where we include all the
known glueball states below the two-particle threshold. We find that an excellent, parameter-free
description of the entropy density between 0:7Tc [0.7 T subscript c] and Tc [T subscript c] is obtained by extending the spectrum with
the exponential spectrum of the closed bosonic string. |
