text: The values of the presently available truncated perturbative expressions for
the pressure of the quark-gluon plasma at finite temperatures and finite chemical
potential are trustworthy only at very large energies. When used down to temperatures
close to the critical one (T-c), they suffer from large uncertainties due to the
renormalization scale freedom. In order to reduce these uncertainties, we perform
resummations of the pressure by applying two specific Pade-related approximants
to the available perturbation series for the short-distance and for the long-distance
contributions. In the two contributions, we use two different renormalization
scales which reflect different energy regions contributing to the different parts.
Application of the obtained expressions at low temperatures is made possible by
replacing the usual four-loop (MS) over bar beta function for alpha(s) by its
Borel-Pade resummation, thus eliminating the unphysical Landau singularities of
alpha(s). The obtained results are remarkably insensitive to the chosen renormalization
scale and can be compared with lattice results-for the pressure p, the chemical
potential contribution Delta p to the pressure, and various susceptibilities.
A good qualitative agreement with the lattice results is revealed down to temperatures
close to T-c.
