Charmonia suppression in nucleus-nucleus interactions at CERN SPS / Arnaldi, R ; Alessandro, B ; Alexa, C ; Arnaldi, R ; Atayan, M ; Baglin, C ; Baldit, A ; Bedjidian, M ; Beolè, S ; Boldea, V et al.
The NA50 experiment at CERN SPS has studied charmonium production in Pb-Pb collisions at 158 GeV/c per nucleon. According to the theoretical predictions the observation of the suppression of the $J/\psi$ production yield is expected to be an unambiguous probe for a phase transition from ordinary nuclear matter towards a state in which quarks and gluons are deconfined.

The production of $\phi , \omega$ and $\rho$ mesons in $p$-, $d$-, S- and Pb- induced reactions at the CERN SPS / Jouan, D ; Alessandro, B ; Alexa, C ; Arnaldi, R ; Atayan, M ; Baglin, C ; Baldit, A ; Bedjidian, M ; Beolè, S ; Boldea, V et al.
From proton, deuteron, S- and Pb-induced reactions, experiments NA38 and NA50 have measured muon pair production with various targets. In particular, the production rates of the $\phi, \omega$ and $\rho$ mesons have been simultaneously extracted and compared. [...]

The NA50 Collaboration studies the J/psi, psi' and Drell-Yan production via their dimuon decay in Pb-Pb interactions at 158 GeV per nucleon at the CERN SPS: the most recent results on charmonium production are presented here..

Results from the NA50 experiment on $J/\psi$ suppression and charged particle pseudorapidity distributions in Pb-Pb collisions / NA50 Collaboration
We report preliminary results on $J/\psi$ suppression in Pb-Pb collisions at 158 GeV/c incident momentum. The new study is based on the most recent data collected with improved experimental conditions and extending over a large centrality range. [...]

Pseudorapidity distributions of charged particles in Pb-Pb collisions at super proton synchrotron energies from the NA50 experiment / NA50 Collaboration
We present the measurements of charged particle pseudorapidity distributions $dN\_{ch}/d \eta$ performed by the NA50 experiment in Pb-Pb collisions at the CERN SPS. Measurements were done at incident energies of 40 GeV ($\sqrt{s}$ = 8.77 GeV) and 158 GeV ($\sqrt{s}$ = 17.3 GeV) per nucleon over a broad impact parameter range. [...]

Study of deconfinement in NA50 / NA50 Collaboration
The J/$\psi$ production in 158 A GeV Pb-Pb interactions is studied, in the dimuon decay channel, as a function of centrality, as measured with the electromagnetic or, alternatively, with the very forward hadronic calorimeters. After a first sharp variation at mid- centrality, both patterns continue to fall down and-exhibit a curvature change at high centrality values. [...]

Transverse-momentum fluctuations in $\pi^{+}p$ and $K^{+}p$ collisions at 250 GeV/c / NA22 Collaboration
We report results on event-by-event fluctuations of transverse momentum, Phi (p/sub t/), in pi /sup +/p and K/sup +/p collisions at 250 GeV/c. For the first time, their dependence on rapidity region, transverse momentum acceptance, multiplicity, mean transverse momentum per event, and on the correlation between transverse momentum and multiplicity are systematically presented.

Results on leptonic probes from NA50 / NA50 Collaboration
The NA50 Collaboration has performed a new measurement of the J/$\psi$ yield in Pb-Pb collisions at 158 GeV/nucleon in improved experimental conditions. Our preliminary analysis of the year 2000 data sample, while confirming the onset of anomalous suppression and the non saturation of the J/$\psi$ / Drell-Yan cross-section ratio, shows that peripheral Pb-Pb interactions follow the normal nuclear absorption pattern, which has in turn been established more precisely thanks to high statistics p-A data. [...]

Transverse momentum distribution of J/$\psi$ produced in Pb-Pb and p-A interactions at the CERN SPS / NA50 Collaboration
Muon pairs produced in Pb-Pb interactions at 158 GeV/c per nucleon and in p-A interactions at 400 GeV/c, together with older S-U results obtained at 200 GeV/c are used to study the transverse momentum and transverse mass distributions of the J/$\psi$. (13 refs)..
