 Nuclear modification factor of electrons from beauty-hadron decays in the $10\%$ most central Pb--Pb collisions at $\sqrt{s_{\rm{NN}}} = 5.02 {\rm TeV}$. Left: Comparison with \Raa of muons from beauty-hadron decays measured by the ATLAS Collaboration . Right: comparison with the measurements of \Raa of electrons from heavy-flavor hadron (beauty plus charm) decays , and with the \Raa of muons from charm-hadron decays measured by the ATLAS Collaboration .
