# Figure 4

 Left: Invariant mass distribution for \Ppsi\ $\rightarrow$ \mmpp\ (upper panel) and \Ppsi\ $\rightarrow$ \eepp\ (bottom panel). The green line shows the wrong sign four-track events. The red line shows the \Ppsi\ signal as described in the text. Right: Transverse momentum distribution of \Ppsi~candidates in the mass range quoted in the figure (around the \Ppsi\ nominal mass).
