Experimental Status Of $J/\psi$ Suppression / Kluberg, L (Paris U., VI-VII ; Ecole Polytechnique) ; Abreu, M C (LIP, Lisbon) ; Alessandro, B (Turin U. ; INFN, Turin) ; Alexa, C (Bucharest U.) ; Arnaldi, R (Turin U. ; INFN, Turin) ; Astruc, J (Orsay, IPN) ; Atayan, M (Yerevan Phys.

The most recent results obtained by experiment NA50 show that the $J /\psi$ cross-section per nucleon-nucleon collision in semi-peripheral Pb-Pb reactions is "normally" suppressed in the sense that it follows the trend already observed from p-p and up to the most central S-U reactions. A clear change of behaviour is observed for more central Pb-Pb collisions which could be due to the transition of normal nuclear matter to its predicted Quark-Gluon Plasma state

J/$\psi$ azimuthal anisotropy relative to the reaction plane in Pb-Pb collisions at 158 GeV per nucleon / on behalf of the NA50 Collaboration
The J/$\psi$ azimuthal distribution relative to the reaction plane has been measured by the NA50 experiment in Pb-Pb collisions at 158 GeV/nucleon. Various physical mechanisms related to charmonium dissociation in the medium created in the heavy ion collision are expected to introduce an anisotropy in the azimuthal distribution of the observed J/$\psi$ mesons at SPS energies.

The J/$\psi$ normal nuclear absorption / NA50 Collaboration
We present a new determination of the ratio of cross-sections ($J/\psi$) /DY as expected for nucleus-nucleus reactions if J/psi would only be normally absorbed by nuclear matter. This anticipated behaviour is based on proton-nucleus data exclusively, and compared, as a function of centrality, with updated S-U results from experiment NA38 and with the most recent Pb-Pb results from experiment NA50..

$J/\psi$ and $\psi'$ production and their normal nuclear absorption in proton-nucleus collisions at 400 GeV / NA50 Collaboration
We report a new measurement of J/psi, psi' and Drell-Yan cross-sections, in the kinematical domain $-0.425<y_{\rm cm}<0.575$ and $-0.5<\cos\theta_{\rm CS}<0.5$, performed at the CERN-SPS using 400 GeV/c incident protons on Be, Al, Cu, Ag, W and Pb targets. The dependence of the charmonia production cross-sections on the size of the target nucleus allows to quantify the so-called normal nuclear absorption. [...]

$\psi^{\prime}$ production in Pb-Pb collisions at 158 GeV/nucleon / NA50 Collaboration
$\psi{prime}$ production is studied in Pb-Pb collisions at 158 GeV/c per nucleon incident momentum. Absolute cross-sections are measured and production rates are investigated as a function of the centrality of the collision. [...]

Bottomonium and Drell-Yan production in p-A collisions at 450 GeV / NA50 Collaboration
The NA50 Collaboration has measured heavy-quarkonium production in p-A collisions at 450 GeV incident energy (sqrt(s) = 29.1 GeV). We report here results on the production of the Upsilon states and of high-mass Drell-Yan muon pairs (m > 6 GeV). [...]
