The preliminary results of J/psi spectra at high transverse momentum (5<p_T<14 GeV/c) in p+p and Cu+Cu collisions at s_NN = 200 GeV are reported. The nuclear modification factor is measured to be 0.9+/-0.2 at p_T>5 GeV/c. The correlations between J/psi and charged hadrons are also studied in p+p collisions to understand the J/psi production mechanism at high p_T.

The STAR collaboration at RHIC presents measurements of Jpsi$to{e^+e^-}$ at mid-rapidity and high transverse momentum ($p_T>5$ GeV/$c$) in pp and central cucu collisions at sNN = 200 GeV. The inclusive Jpsi production cross section for cucu collision s is found to be consistent at high $p_T$ with the binary collision-scaled cross section for pp collisions, in contrast to previous measurements at lower $p_T$, where a suppression of Jpsi production is observed relative to the expectation from binary scaling. Azimuthal correlations of $J/psi$ with charged hadrons in pp collisions provide an estimate of the contribution of $B$-meson decays to Jpsi production of $13% pm 5%$.

The results on J/psi pT spectra in 200 GeV p+p and Au+Au collisions at STAR with pT in the range of 3-10 GeV/c are presented. Nuclear modification factor of high-pT J/psi is found to be consistent with no suppression in peripheral Au+Au collisions an d significantly smaller than unity in central Au+Au collisions. The J/psi elliptic flow is measured to be consistent with no flow at pT < 10 GeV/c in 20-60% Au+Au collisions.

We report results on J/psi-hadron azimuthal angular correlations in 200 GeV p+p collision in the STAR experiment at RHIC. The extracted B-hadron feed-down contribution to inclusive J/psi yield is found to be 10-25% in 4<p_T<12 GeV/c and has no signif icant center-of-mass energy dependence from RHIC to LHC. The p_T spectrum of charged hadron associated with high-p_T J/psi triggers on the away side is found to be consistent with that from di-hadron correlations. J/psi signal from partially produced Au+Au 39 GeV data will also be presented to demonstrate STARs J/psi capability at RHIC low energy run.

The NA60 experiment studies dimuon production in In-In and p-A collisions at the CERN SPS. We report recent results on jpsi production, measured through its muon pair decay. As a function of centrality, we show that in In-In the jpsi yield is suppres sed beyond expectations from nuclear absorption. We present also for the first time results on jpsi production in p-A collisions at 158 GeV, the same energy of the nucleus-nucleus data. For both p-A and In-In we show preliminary results on psip suppression. Finally, we have studied the kinematical distributions of the jpsi produced in In-In collisions. We present results on transverse momentum and rapidity, as well as on the angular distribution of the jpsi decay products.

We report $J/psi$ spectra for transverse momenta $p_T$> 5 GeV/$c$ at mid-rapidity in p+p and Au+Au collisions at sqrt(s_{NN}) = 200 GeV.The inclusive $J/psi$ spectrum and the extracted $B$-hadron feed-down are compared to models incorporating differe nt production mechanisms. We observe significant suppression of the $J/psi$ yields for $p_T$> 5 GeV/$c$ in 0-30% Au+Au collisions relative to the p+p yield scaled by the number of binary nucleon-nucleon collisions in Au+Au collisions. In 30-60% collisions, no such suppression is observed.The level of suppression is consistently less than that of high-$p_T$ $pi^{pm}$ and low-$p_T$ $J/psi$.
