Figure 4

Invariant cross section (left) and yield (right) of electrons from beauty-hadron decays as a function of transverse momentum in minimum-bias p-Pb collisions at $\sqrt{s_{\rm NN}}=5.02$ TeV and in the 20% most central Pb-Pb collisions at $\sqrt{s_{\rm NN}}=2.76$ TeV. The pp reference spectra scaled by the number of nucleons in the Pb nucleus (A = 208) and by $\langle T_{\rm AA} \rangle$, respectively, are shown as well. The vertical bars represent the statistical uncertainties, the boxes indicate the systematic uncertainties. The pp and p-Pb normalisation uncertainties of 3.5% and 3.7% as well as the one of the nuclear overlap function $\langle T_{\rm AA} \rangle$ of 3.9% are not shown.
