Description
The ALICE experiment at the Large Hadron Collider (LHC) has been designed in order to characterize the quark gluon plasma (QGP) in high-energy heavy-ion collisions. D mesons are powerful probes of the medium since the charm quarks are produced at the early stage of the collision and experience its entire evolution. In particular, the anisotropy parameter $v_2$ of D mesons is sensitive to the degree of thermalization of charm quarks within the QGP medium.
The performance of the Q-cumulants and Scalar Product methods used to measure the $v_2$ of D mesons at mid-rapidity in Pb-Pb collisions at $\sqrt{s_{NN}}=2.76$ TeV will be shown.
In particular, results for $\rm{D^{0}}$ and $\rm{D^{*}}$ obtained in the $\rm{D^{0}} \rightarrow K \pi$ and $\rm{D^{*}} \rightarrow \rm{D^{0}} \pi$ decay channels will be reported.
