Figure 4

Inclusive $\Upsilon$ $\raa$ as a function of rapidity measured in Pb-Pb collisions at $\snn=2.76$ GeV by ALICE in $2.5< y< 4$ and CMS in $|y|< 2.4$, compared with the calculations from a transport (top) and a dynamical (bottom) model (see text for details). Open points are reflected with respect to the measured ones and the same conventions as in Fig. 2 are used to show the uncertainties. The relative correlated uncertainty on the ALICE measurement is $7\%$ (and is shown as a box at unity).
