In a
system of deconfined quarks and gluons heavy quarkonium states are
subject to dissociation via static mechanisms such as color screening
or dynamic ones such as gluon scatterings. This leads to a suppression
of hidden charm states, such as the J/Ψ. On the other hand,
statistical hadronization models predict an enhanced production of
hidden charm states for sufficiently high charm densities. We present
first preliminary STAR results on J/Ψ production via electron-positron
decay pairs in p+p and Au+Au collisions at sqrt(s_NN) = 200$ GeV.
J/Ψ measurements in Au+Au collisions were primarily
carried out with the STAR Time Projection Chamber (TPC). For J/Ψ measurements
in p+p collisions, a special trigger was used and reconstruction
was carried out with the TPC and the Barrel Electromagnetic Calorimeter.
The implications of our measurements to models that predict copious
J/$\Psi$ production via Statistical Hadronization are discussed.
