Description
Heavy flavor production is a sensitive probe of the initial gluon density
in the nucleon and is affected by the entire evolution of the collision.
Besides, it is a process which can be calculated by perturbative QCD
because of their large mass.
The PHENIX experiment at RHIC studied the heavy flavor production
for a broad momentum and rapidity ranges using its semileptonic and
$J/\psi$ decays in $p+p$, $p+A$ and $Au+Au$ collisions
at $\sqrt{s_{NN}}$=200GeV.
In this talk, the recent experimental results will be presented
and compared with theoretical models which describe
heavy quark production, gluon distribution modifications
in nucleus and its energy loss in the medium created in Au+Au collisions.
