Quarkonia production in the STAR experiment    [PDF]

Barbara Trzeciak for the STAR Collaboration
In this proceedings the recent STAR results of $J/\psi$ and $\Upsilon$ production in $p+p$, $d$+Au and Au+Au collisions at $\sqrt{s_{NN}}$ = 200 GeV at mid-rapidity are reported. $J/\psi$ $p_{T}$ spectra in $p+p$ and Au+Au collisions for both low and high $p_{T}$ are shown. $J/\psi$ nuclear modification factor ($R_{AA}$) in $d$+Au and Au+Au collisions and $\Upsilon$ $R_{AA}$ in Au+Au collisions are reported. Also, $J/\psi$ polarization in $p+p$ collisions and $J/\psi$ $v_{2}$ for semi-central Au+Au collisions are presented.
