D-meson production in Pb-Pb collisions with ALICE at the LHC

Heavy quarks, like charm and beauty, are sensitive probes to investigate the colour-deconfined medium created in high-energy heavy-ion collisions, the Quark–Gluon Plasma (QGP). The ALICE Collaboration measured the production of D 0 , D + , D *+ and D +s in Pb–Pb collisions at sNN=5.02TeV . The measu...

Sumario:Heavy quarks, like charm and beauty, are sensitive probes to investigate the colour-deconfined medium created in high-energy heavy-ion collisions, the Quark–Gluon Plasma (QGP). The ALICE Collaboration measured the production of D 0 , D + , D *+ and D +s in Pb–Pb collisions at sNN=5.02TeV . The measurement of the nuclear modification factor ( R AA ) provides information on the in-medium parton energy loss. In addition, the comparison between D +s and the non-strange D-meson R AA allows to investigate possible modifications of the charm-quark hadronisation mechanism in the QGP. The most recent results for these observables, which were obtained by analysing the latest 2018 data sample of Pb–Pb collisions as well as the comparison with theoretical model calculations, are presented.
