The average transverse momentum $\langle p_{T} \rangle$ of inclusive $\textrm{J}/\psi$ measured at mid-rapidity ($|y| < 0.8$) in centrality selected Pb-Pb collisions (filled circles) and pp collisions (open circles) at $\sqrt{s_{NN}}$ =2.76 TeV as a function of the number of participants $\langle N_{part} \rangle$. The uncorrelated systematic uncertainties (type II) are depicted by the open boxes Left panel: A comparison to results obtained by the PHENIX collaboration for Au-Au and Cu-Cu collisions at $\sqrt{s_{NN}}$ = 0.2 TeV (open and filled diamonds) and by the NA50 collaboration for Pb-Pb collisions at $\sqrt{s_{NN}}$ = 17.3 GeV (crosses). The $\langle p_{T} \rangle$ values are calculated for NA50 and PHENIX in the $p_{T}$ interval 0 - 5 GeV$/c$, while for ALICE the $p_{T}$ interval is 0 - 10 GeV$/c$ Right panel: $\langle p_{T} \rangle$ is compared to theory predictions by Zhou etal. and Zhao et al. for the $p_{T}$ interval 0 - 10 GeV$/c$.
