Reconstructed (raw) yields of $\phi$ (stars) and $\mathrm {\Xi^{-}+\overline{\Xi}^{+}}$ (diamonds) as a function of $\pT$ With the current statistics, 4$ \pT$ bins are used for the $\phi$ ([0.7-1.0], [0.7-1.5], [1.5-2.0]and [2.0-3.0]$ $GeV/c) and $3 \pT$ bins for the $\mathrm {\Xi^{-}+\overline{\Xi}^{+}}$ ([0.6-1.4], [1.4-2.0] and [2.0-3.0]$ $GeV/c) Uncertainties correspond to the statistics (i.e. the number of reconstructed particles)and the systematics from the signal extraction. They are represented by the vertical error bars(the horizontal ones give the bin width).
