Abstract

Pade approximants (PA) are constructed from the perturbative coefficients of the free energy through O(g^5) in hot QCD. PA is shown to reduce the renormalization-scale dependence substantially even at temperature (T) as low as 250 MeV. Also, Pade summation predicts that the free energy does not deviate more than 10 % from the Stefan-Boltsman limit for T > 250 MeV.
