Open-charm meson elliptic flow measurement in Pb–Pb collisions at √(sNN)=2.76TeV with ALICE at the LHC

The ALICE experiment is one of the four large experiments at the Large Hadron Collider (LHC), and it is dedicated to the study of ultra-relativistic heavy-ion collisions, with the goal of investigating the properties of the high-density state of QCD matter produced in these collisions. The study of D meson azimuthal anisotropy and the measurement of its elliptic flow (ν2) can provide insight on the degree of thermalisation of charm quarks in the medium and on the charm hadronization mechanism. We present the measurement of the D+ and D0 meson ν2 in Pb–Pb collisions at √(sNN)=2.76TeV at the LHC with ALICE. We discuss the details of the analysis and we show the results obtained from data samples collected in 2011
