Figure 6

Relative \mpt  of \jpsi mesons for backward and forward rapidity as a function of the relative charged-particle pseudorapidity density. The bars show the statistical uncertainties, the boxes the systematic ones. The data for charged particles (h$^\pm$) are included for comparison. The latter are for $|\etacms|< 0.3$ and with \pt  in the range 0.15 to 10 \gevc  and have an additional normalisation uncertainty of 3.4\%
