Elliptic flow of identified hadrons in Pb-Pb collisions at sNN=2.76 TeV

The elliptic flow coefficient (v2) of identified particles in Pb-Pb collisions at √ sNN = 2.76 TeV was measured with the ALICE detector at the Large Hadron Collider (LHC). The results were obtained with the Scalar Product method, a two-particle correlation technique, using a pseudo-rapidity gap of |∆η| > 0.9 between the identified hadron under study and the reference particles. The v2 is reported for π ±, K±, K0 S , p+p, φ, Λ+Λ, Ξ −+Ξ + and Ω−+Ω + in several collision centralities. In the low transverse momentum (pT) region, pT 3 GeV/c.
