Anisotropic Flow of Charged Particles at High Transverse Momentum in 2.76 TeV Pb-Pb Collisions at the LHC from ALICE experiment

stand the collision dynamics. We report on measurements of anisotropic flow components v2, v3, and v4 for unidentified charged particles, pions and protons in PbPb collisions at √ sNN = 2.76 TeV recorded by the ALICE experiment at the LHC. v2 is presented for a wide range of particle transverse momentum up to pT = 20 GeV/c. The particle v2 is finite, positive and approximately constant for pT > 8 GeV/c. The proton v2 is higher than that of the pion up to about pT = 8
