Efficiency of $\Kzs$ (open circles), $\mathrm {\Lambda}$ (open squares) and $\mathrm {\overline{\Lambda}}$(open triangles) as a function of $\pT$ The uncertainties correspond to the statistics in Monte Carlo samples used to compute thecorrections The efficiency is limited by the branching ratio represented by a solid arrow for $\Kzs$ (0.692)and by a dashed arrow for $\mathrm {\Lambda}$ and $\mathrm {\overline{\Lambda}}$ (0.639) .
