Description
The ALICE experiment at the LHC is dedicated to the study of ultra-
relativistic heavy-ion collisions, with the aim of investigating the high-density
color deconned state of strongly interacting matter that is expected to be
formed in these collisions.
Heavy quarks serve as a probe of the dynamics of the medium since they are
produced at the early stages of the collisions and they propagate through the
created matter.
The D meson azimuthal anisotropy (v2) is expected to bring insights into the
degree of thermalization of charm quarks within the quark-gluon plasma.
A non-zero v2 at low transverse momentum indicates a collective motion of
charm quarks with respect to the bulk of created matter, while at high trans-
verse momentum v2 is sensitive to the path length dependence of the charm
quark energy loss within the medium.
The measurement of D0, D+ and D+ elliptic
ow and D0 RAA versus event
plane in semi-central Pb{Pb collisions at
p
sNN = 2:76 TeV will be pre-
sented. D mesons have been reconstructed via their hadronic decay channels
(D0 ! K+, D+ ! K++ and D+ ! D0+) in the central rapidity re-
gion.
