π0-hadron correlations in pp and Pb-Pb collisions and π0 elliptic flow in Pb-Pb collisions measured at the ALICE experiment

The study of the azimuthal correlation and anisotropy with π0 offers a powerful way to investigate the properties of strongly-interacting matter created in ultra-relativistic heavy-ion collisions. In this talk, we present the measurement of two-particle correlations of π0 trigger particles with associated charged particles versus azimuthal angle difference (Δφ) in pp and central Pb-Pb collisions at sNN=2.76 TeV, as well as the measurement of the elliptic flow (v2) of π0 in Pb-Pb collisions at sNN=2.76 TeV at the ALICE experiment. π0 are detected by the ALICE electromagnetic calorimeter EMCal for transverse momenta 8
