\kzero, \Lamboth, \Xiboth, and \Omboth particle yield ratios to the pion yield in \PbPb collisions at \fivenn (squares), compared to results in \pp collisions at \seven  and \thirteen  (hollow and full circles, respectively), in \pPb collisions at \five  (hollow diamonds), and in \PbPb collisions at \twosevensixnn  (stars). Error bars show the statistical uncertainty, while boxes represent the total systematic uncertainty. \epf  predictions are reported for the top \PbPb energy as solid lines.
