The production of the J/Psi is measured by the PHENIX experiment in
sqrt(sNN)=200GeV Au+Au collisions. The scientific goal of this measurement
is to investigate the nature of hot and dense nuclear matter through the
unique properties of the J/Psi. Recent experimental results by the NA50 at
CERN showed anomalous suppression in central Pb+Pb collisions at low energy.

We know that there are large number of possible effect impacting their final
yield of J/Psi. In this talk a survey of the theoretical models is presented
and J/Psi PHENIX measurements are compared.
