Figure 4

Nuclear modification factor $R_{\rm{AA}} $ of charged particles measured by ALICE in the most central Pb-Pb collisions (0-5%) in comparison to results from CMS and model calculations . The boxes around the data denote $p_{{\rm T}}$-dependent systematic uncertainties. For CMS statistical and systematic uncertainties on $R_{\rm {AA}}$ are added in quadrature. The systematic uncertainties on the normalization which are related to $\langle T_{\rm {AA}} \rangle$ and the normalization of the pp data are added in quadrature and shown as boxes at $R_{\rm{AA}} =1$ (the right-most is for CMS).
