- Abstract We report measurement of elliptic flow \upsilon_{2}(p_{T}) in extended transverse momentum range for the identified cases of K_{s}^{0} (<8.5 GeV/c), \Lambda and \bar{\Lambda} (<7.5 GeV/c) in Pb- Pb 20-40% central collisions at \sqrt{s_{NN}}= 2.76 TeV measured with the ALICE detector at LHC. While K_{s}^{0} 's reach a maximum of \upsilon_{2}=0.167\pm0.0007(stat) at p_{T}\approx3 Gev/c, the baryon (anti-baryon) \upsilon_{2}(p_{T}) continues to rise until it reaches a maximum of \upsilon_{2}(p_{T})=0.213\pm0.0013(stat) \left(0.214\pm0.0014(stat)\right) at p_{T}\approx4 GeV/c. For larger p_{T} , the \upsilon_{2}(p_{T}) values exhibit a gradual decrease for all three cases. Quark scaling properties are also examined, indicating that at... (More)

Quark scaling properties are also examined, indicating that at intermediate and high p_{T} scaling does not hold for strange particles \upsilon_{2}(p_{T}) . (Less)
