Mean transverse momenta for \ks and \ph are compared with those for \kz, $\Lambda$+$\overline{\Lambda}$, $\Xi^{-}$+$\overline{\Xi}^{+}$, and $\Omega^{-}$+$\overline{\Omega}^{+}$ in pp collisions at \rs as a function of \dnc . The values for $\Xi^{-}$+$\overline{\Xi}^{+}$ are shifted horizontally for visibility. Bars represent statistical uncertainties, open boxes represent total systematic uncertainties, and shaded boxes show the systematic uncertainties that are uncorrelated between multiplicity classes.
