description

Abstract The high- P T particle production anisotropy in Pb–Pb collisions at s N N = 2.76 TeV studied by the ALICE experiment is presented. The event plane and the four-particle cumulant method are used to extract the ν 2 and ν 3 flow coefficients of unidentified charged hadrons, pions and protons out to p T = 20 GeV / c . The observed non-zero values of the elliptic flow in the high- p T region where the collective phenomena are negligible are discussed.
