Transverse momentum distributions of J/ψ produced in Pb-Pb and p-A interactions at the CERN SPS

ALL DATA SHOULD BE CONSIDERED AS PRELIMINARY, except the 1995 and 1996 data already published in Phys. Lett. B 499 (2001) 85-96.

• Fig. 1 of proceedings: Average squared transverse momentum of the J/ψ as a function of the transverse energy, as measured in the several Pb-Pb data taking periods.
• Fig. 2 of proceedings: Average squared transverse momentum of the J/ψ a a function of the length of matter traversed in the initial state, for three diffrent energies.
• Fig. 3 of proceedings: Inverse slope parameter, T, of the J/ψ as a function of the energy density. The lines are linear fits to the data points, for each beam energy.
• Fig. 4 of proceedings: Same as previous figure, after rescaling all data sets to 158 GeV. The inset shows the slopes of the linear fits (Fig. 3) vs. center of mass energy.
• p-Pb Pt spectrum for 2000:Transverse momentum spectrum of J/ψ for the year 2000 p-Pb data.
• Pb-Pb Pt spectrum for 1996:Transverse momentum spectrum of J/ψ for the year 1996 Pb-Pb data.
