【 摘 要 】

Heavy quarks are a powerful probe for investigating the properties of the Quark- Gluon Plasma created in heavy-ion collisions, since they are produced in initial hard scattering processes and experience all the stages of the medium evolution. ALICE has measured the production of D0D+, D∗+and D+s mesons at central rapidity in their hadronic decay channels in various collision systems and energies. We present recent results for D-meson production measured by the ALICE Collaboration in pp collisions at √s = 7 and 2.76 TeV, Pb-Pb collisions at √s= 2.76 TeV and p-Pb collisions at √s= 5.02 TeV.
