Elliptic flow of identified particles in Pb–Pb collisions at the LHC

The elliptic flow coefficient, v2 , is presented for π± , K± , KS0 , p+p¯ , ϕ , Λ+Λ¯ , Ξ−+Ξ¯+ , Ω−+Ω¯+ in Pb–Pb collisions at sNN=2.76 TeV with the ALICE detector. Results obtained with the scalar product method are reported as a function of transverse momentum, pT , out to pT=6 GeV/c at different c...

description The elliptic flow coefficient, v2 , is presented for π± , K± , KS0 , p+p¯ , ϕ , Λ+Λ¯ , Ξ−+Ξ¯+ , Ω−+Ω¯+ in Pb–Pb collisions at sNN=2.76 TeV with the ALICE detector. Results obtained with the scalar product method are reported as a function of transverse momentum, pT , out to pT=6 GeV/c at different collision centralities. For pT<2 GeV/c , v2 exhibits a particle mass dependence. Particles tend to group into mesons and baryons for pT>3 GeV/c . Deviations from the number of constituent quark scaling at the level of ±20% are found for pT>2–3 GeV/c . The results are compared to hydrodynamic calculations coupled to a hadronic cascade model.
