MEASUREMENT OF ELLIPTIC FLOW OF D0 IN Pb-Pb COLLISIONS AT √sNN=2.76 TeV WITH ALICE AT THE LHC

The study of particle azimuthal anisotropy in heavy-ion collisions provides insight on the collective hydrodynamic expansion of the system and on its equation of state. The measurement of the elliptic flow, v(2), of D mesons compared to that of light hadrons is expected to be sensitive to the degree of thermalization of charm quarks within the quark-gluon plasma. The first measurement of v(2) of D-0 mesons with the ALICE detector at the LHC will be presented. The preliminary results obtained with the first Pb-Pb run at LHC show a hint of non-zero v(2) for transverse momenta obeying 2 < PT < 5 GeV/c.
