Production anisotropy of h±, π± and p/p¯ at high-pT in Pb-Pb collisions at sNN=2.76TeV

The high-PT particle production anisotropy in Pb-Pb collisions at sNN=2.76TeV studied by the ALICE experiment is presented. The event plane and the four-particle cumulant method are used to extract the ν2 and ν3 flow coefficients of unidentified charged hadrons, pions and protons out to pT=20GeV/c. The observed non-zero values of the elliptic flow in the high-pT region where the collective phenomena are negligible are discussed.
