Query: The thermodynamic properties of weakly interacting quark gluon plasma
  via the one gluon exchange interaction   The thermodynamic properties of the quark gluon plasma($QGP$) as well as its
phase diagram are calculated as a function of baryon density (chemical
potential) and temperature. The $QGP$ is assumed to be composed of the light
quarks only, i.e. the up and the down quarks, which interact weakly and the
gluons which are treated as they are free. The interaction between quarks is
considered in the framework of the one gluon exchange model which is obtained
from the Fermi liquid picture. The bag model is used, with fixed bag pressure
(${\cal B}$) for the nonperturbative part and the quantum chromodynamics
($QCD$) coupling is assumed to be constant i.e. no dependence on the
temperature or the baryon density. The effect of weakly interacting quarks on
the $QGP$ phase diagram are shown and discussed. It is demonstrated that the
one gluon exchange interaction for the massless quarks has considerable effect
on the $QGP$ phase diagram and it causes the system to reach to the confined
phase at the smaller baryon densities and temperatures. The pressure of
excluded volume hadron gas model is also used to find the transition
phase-diagram. Our results depend on the values of bag pressure and the $QCD$
coupling constant which the latter does not have a dramatic effect on our
calculations . Finally, we compare our results with the thermodynamic
properties of strange quark matter and the lattice $QCD$ prediction for the
$QGP$ transition critical temperature.
