Open heavy-flavor production in Pb-Pb collisions measured with ALICE at the LHC

ORAL

Abstract

Heavy-flavor quarks (charm and beauty) are created in the first moments of a heavy-ion collision via hard partonic scattering processes. Therefore, they experience the full evolution of the collision and interact with constituents of the hot and dense QCD medium produced, the Quark-Gluon-Plasma (QGP), a state of matter in which quarks and gluons are deconfined. We can gain insight into the microscopic processes responsible for heavy-quark energy loss in the QGP by measuring heavy-flavor hadrons and their decay products. 

With the ALICE detector, heavy-flavor measurements are conducted over a wide rapidity range. At mid-rapidity, D mesons, $\Lambda_{\rm c}^{+}$ baryons, heavy-flavor decay electrons, and beauty-decay electrons are measured, while heavy-flavor decay muons are measured at forward rapidity using the ALICE muon spectrometer. In this talk, the latest heavy-flavor measurements in Pb-Pb at $\sqrt{s_{\rm NN}}$ = 5.02 TeV will be presented. This includes measurements of D mesons, $\Lambda_{\rm c}^{+}$ baryons, and beauty-decay leptons.
