(left) \meanpt as a function of \avdndeta for \kzero, \lmb, \Xit, and \Omt particle production in \PbPb collisions at \fivenn at midrapidity (square markers). Results from \pp~ and \pPb~ collisions at the same center-of-mass energy are also reported as circles and open diamonds, respectively. Error bars correspond to the statistical uncertainty, while boxes correspond to the total systematic uncertainty. Solid lines are predictions from the \epf~ model. (right) \lmb/\kzero ratio as a function of \pt for the 0--10\% most central (red), 40--50\% intermediate (green) and 80--90\% most peripheral (blue) centrality classes. Error bars correspond to the statistical uncertainty, while boxes correspond to the total systematic uncertainty. \epf~ predictions, scaled to the total particle yields in the corresponding centrality class, are reported as solid lines.
