Description

The ALICE experiment at the LHC studies Pb-Pb and pp collisions with the aim of investigating the properties of the high-density state of strongly-interacting matter, expected to be produced in Pb-Pb collisions. Heavy quarks are sensitive probes to test the medium properties, since they are formed at shorter time scale with respect to the deconfined state. The elliptic flow v2 of D meson compared to that of light hadrons is expected to bring insights into the degree of thermalization of charm quarks within the quark-gluon plasma. D meson have been reconstructed in their hadronic decay channels (D0 --> K-pi+, D+-->K-pi+pi+, D*+-->D0pi+), in the central rapidity region in Pb-Pb collisions at sqrt{s_NN}=2.76 TeV, with data collected in the 2011 run. The measurement of the D meson elliptic flow in semi-central Pb-Pb collisions will be presented.
