Description
The ALICE experiment at the LHC studies ultra-relativistic Pb-Pb
collisions with the aim of investigating the properties of the
high-density state of strongly-interacting matter, expected to be
produced in heavy-ion collisions.
Heavy quarks are sensitive probes of the medium properties, since they
are formed on a shorter time scale with respect to the medium.
The elliptic flow ($v_{2}$) of low $p_{\rm T}$ D mesons
can bring insight into the degree of thermalization of charm quarks
within the medium. The suppression of the yield of high-$p_{\rm T}$ D
mesons, measured in different intervals of azimuthal
angles relative to the reaction plane, can give access to the
path-length dependence of parton energy loss.
${\rm D}^0 \rightarrow {\rm K}^- \pi^+$ decays have been reconstructed in the
central rapidity region in Pb-Pb collisions at $\sqrt{s_{\rm NN}}$ = 2.76 TeV, using data recorded during the year 2011.
The final results on the $\rm D^0$ meson azimuthal anisotropy in Pb-Pb
collisions, for different centrality classes, will be presented and the comparison with theoretical
models will be described.
