Figure Caption

Invariant mass (left panel) and pseudoproper decay length (right panel) distributions of \jpsi candidates with maximum likelihood fit projections superimposed. The distributions in the figures correspond to selected candidates with $1.5 < \pt < 3.0$~\GeVc in the centrality class 30--50\%. The pseudoproper decay length distribution is shown for \jpsi candidates reconstructed under the \jpsi mass peak, i.e. for $2.92 < m_{\rm ee} < 3.16$~GeV/$c^{2}$, for display purposes only. The $\chi^{2}$ values, obtained by comparing the binned distributions of data points and the corresponding projections of the total fit function, are also reported.
