The ALICE Collaboration at the LHC aims at investigating the properties of hot and dense QCD matter, the quark-gluon plasma (QGP), created in ultra-relativistic heavy-ion collisions. Heavy quarks are created in initial hard scattering process, therefore they are effective probes of the evolution of the QGP. Since beauty quarks are four times heavier than charm quarks, we can get an insight into the in-medium mass dependent energy loss by comparing beauty with charm.
In ALICE, beauty production can be studied via semi-electronic decays of beauty hadrons. The yield of electrons coming from open beauty-hadron decays is obtained by fitting the impact parameter distribution with templates of different electron sources. In this contribution, the measurements of electrons from beauty-hadron decays in Pb-Pb collisions at $\sqrt{\it{s}_{\rm{NN}}}$ = 5.02 TeV are presented.
