Description
The elliptic flow is an important observable to probe the properties
of the system created in heavy-ion collisions. As the collectivity
is built up throughout the collision evolution, information about space-momentum correlations developed during the partonic phase can be masked later by interactions during the hadronic one. Multi-strange particles are believed to have smaller hadronic cross-sections and therefore their elliptic flow is expected to be more sensitive to the quark-gluon plasma phase than to the hadronic one. In this talk, we present the elliptic flow of strange and multi-strange particles (K$^{0}_{s}$, $\Lambda$, $\Xi$, $\Omega$, $\phi$) measured at midrapidity by ALICE in Pb-Pb collisions at $\sqrt{s_{NN}}=2.76$
TeV. We compare our results to hydrodynamic model calculations and the measurements at RHIC energies.
