Charmonia Production at the CERN/SPS

We present the final results of experiment NA50 on charmonia production in Pb-Pb interactions at 158 A GeV. A strong increasing suppression is observed with increasing centrality, for both the $J\psi$ and $\psi^{prime}$ resonances. We also present new developments regarding the jpsi and psiprime nor...

description We present the final results of experiment NA50 on charmonia production in Pb-Pb interactions at 158 A GeV. A strong increasing suppression is observed with increasing centrality, for both the $J\psi$ and $\psi^{prime}$ resonances. We also present new developments regarding the jpsi and psiprime normal nuclear absorption determinations deduced from proton-nucleus data only. Their comparison with Pb-Pb results allows us to conclude that the $J\psi$ anomalous suppression sets in at mid-centralities while the S-U results show a reasonable agreement with the p-A behavior. The $\psi^{prime}$ suffers a significantly stronger suppression already in S-U interactions, which continuously increases in the Pb-Pb system, and is completely incompatible with the expected behavior deduced from p-A collisions.
