Figure 3

Transverse momentum distributions $\rm{d} N/\rm{d}\pt$ of prompt $\rm D_s^+$ mesons in the 0-10% (left panel) and 20-50% (right panel) centrality classes in Pb-Pb collisions at $\snn=2.76 \rm TeV$. Statistical uncertainties (bars), systematic uncertainties from data analysis (empty boxes) and systematic uncertainties due to beauty feed-down subtraction (shaded boxes) are shown. The reference pp distributions $\langle T_{\rm AA}\rangle \rm{d}\sigma/\rm{d}\pt$ are shown as well.
