    "abstract": "A transport approach including a leakage effect for J/psi\u0027s in the transverse\nphase space is used to calculate the ratios between the J/psi transverse\nmomentum distributions in several centrality bins for Pb-Pb collisions at E/A =\n160 GeV. From the comparison with the CERN-SPS data, where the centrality is\ncharacterized by the transverse energy Et, the leakage effect is extremely\nimportant in the region of high transverse momentum and high transverse energy,\nand both the threshold and the comover models can describe the ratio well for\nall centrality bins except the most central one (Et \u003c 100 GeV), for which the\ncomover model calculation is considerably better than the threshold one.",
