Invariant-mass (left) and pseudo-proper decay-length (right) distributions for \jpsi candidates, measured in charged-particle jets with $7\ptjetch15$~\GeVc, with superimposed projections of the maximum-likelihood fit for the intervals $0.4 \z 0.5$ and $0.90 \z 0.95$ in the top and bottom panels, respectively. The pseudo-proper decay-length distributions are shown for \jpsi candidates reconstructed in the invariant-mass range $2.92 \mee 3.16$~\GeVmass for display purposes only.
