Armenteros-Podolanski distribution for V0 candidates showinga clear separation between $\Kzs$, $\mathrm {\Lambda}$ and $\mathrm {\overline{\Lambda}}$ The $\gamma$ converting to $e^{+}e^{-}$ with the detector material arelocated in the low $q_{T}$ region, where $q_{T}$ is the momentum componentperpendicular to the parent momentum vector. |  |
