Query: Near-threshold production of the multi-strange $\Xi^-$ hyperon   The yield for the multi-strange $\Xi^{-}$ hyperon has been measured in 6 AGeV
Au+Au collisions via reconstruction of its decay products $\pi^{-}$ and
$\Lambda$, the latter also being reconstructed from its daughter tracks of
$\pi^{-}$ and p. The measurement is rather close to the threshold for $\Xi^{-}$
production and therefore provides an important test of model predictions. The
measured yield for $\Xi^{-}$ and $\Lambda$ are compared for several
centralities. In central collisions the $\Xi^{-}$ yield is found to be in
excellent agreement with statistical and transport model predictions,
suggesting that multi-strange hadron production approaches chemical equilibrium
in high baryon density nuclear matter.
