bibo_abstract:
- We present a new method for the evaluation of the perturbative expansion of the
QCD pressure which is valid at all values of the temperature and quark chemical
potentials in the deconfined phase and which we work out up to and including order
g(4) accuracy. Our calculation is manifestly four-dimensional and purely diagrammatic-and
thus independent of any effective theory descriptions of high temperature or high
density QCD. In various limits, we recover the known results of dimensional reduction
and the hard dense/thermal loop (HDL/HTL) resummation schemes, as well as the
equation of state of zero-temperature quark matter, thereby verifying their respective
validity. To demonstrate the overlap of the various regimes, we furthermore show
how the predictions of dimensional reduction and HDL resummed perturbation theory
agree in the regime T similar to root g mu. At parametrically smaller temperatures
T similar to g mu, we find that the dimensional reduction result agrees well with
those of the nonstatic resummations down to the remarkably low value T approximate
to 0.2m(D), where m(D) is the Debye mass at T=0. Beyond this, we see that only
the latter methods connect smoothly to the T=0 result of Freedman and McLerran,
to which the leading small-T corrections are given by the so-called non-Fermi-liquid
terms, first obtained through HDL resummations. Finally, we outline the extension
of our method to the next order, where it would include terms for the low-temperature
entropy and specific heats that are unknown at present.@eng
