Description
We report the measurements of elliptic flow for identified particles produced in Pb--Pb collisions at $\sqrt{s_{\rm NN}} = 2.76$ TeV with the ALICE detector at the LHC.
The second Fourier coefficient, $v_2$, measured with the scalar product method with a large pseudo-rapidity gap of $|\Delta\eta| > 2.0$, is reported for $\pi$, ${\rm K}^{\pm}$, ${\rm K}^0_s$, p ($\overline{\mathrm{p}}$), $\phi$, $\Lambda$ ($\overline{\mathrm{\Lambda}}$), $\Xi$ and $\Omega$.
We will present the transverse momentum $p_{\mathrm{T}}$ dependence of the $v_2$ of each particle for several centrality classes. In the low $p_{\mathrm{T}}$ region ($p_{\mathrm{T}} < 2$ GeV/$c$) our data are described fairly well by hydrodynamical calculations. We will discuss our results in the intermediate $p_{\mathrm{T}}$ region $2 < p_{\mathrm{T}} < 5$ GeV/$c$, where the scaling with the number of constituent quarks was first reported at RHIC energies.
