Mean transverse momentum of $\pi^+$, $\rm K^+$, $\rm K^{*0}$, p, and $\Phi$ in Pb-Pb collisions at $\snn$ = 2.76 TeV (filled symbols) as a function of $\langle N_{part} \rangle$. Also shown are $\langle p_{\rm T} \rangle$ values for the resonances in pp collisions at $\sqrt{s}$ = 7 TeV (open symbols). The measurements for central and mid-central $\Phi$ and p have been shifted horizontally for visibility.
