Figure 3

Left: Invariant mass distribution of \lplp\ pairs. The dashed green line corresponds to the background description. The solid magenta and red line correspond to Crystal Ball functions representing the \Jpsi\ and \Ppsi\ signals, respectively. The solid blue line corresponds to the sum of background and signal functions. Right: Transverse momentum distribution of \Ppsi\ candidates in the mass range quoted in the figure (around the \Ppsi\ mass).
