Elliptic flow of identified hadrons in Pb-Pb collisions at s N N = 2. 76 s₍₍=2. 76 TeV

The elliptic flow coefficient (v 2 ) of identified particles in Pb-Pb collisions at s NN = 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 || > 0.9 between the identified hadron under study and the reference particles. The v 2 is reported for , K , K 0 S , p+p, , +, -+ + and -+ + in several collision centralities. In the low transverse momentum (p T ) region, p T 3 GeV/c.
