Multi-strange baryon elliptic flow in Pb-Pb collisions at sqrt {s_{NN} } = 2.76 TeV measured with the ALICE detector

We present the results on elliptic flow with multi-strange baryons produced in Pb-Pb collisions at $sqrt {s_{NN} } $ = 2.76 TeV. The analysis is performed with the ALICE detector at LHC. Multi-strange baryons are reconstructed via their decay topologies and the v ₂ measurements are analyzed with the two-particle scalar product method. The p _T differential v ₂ values are compared to the viscous hydrodynamical (VISH2+1) model calculation and to the STAR measurements in Au-Au collisions at $sqrt {s_{NN} } $ = 200 GeV. We found that the model describes ?? and ??v ₂ measurements within uncertainties. The differential v ₂ of ?? and ?? is similar to the STAR measurements at 200 GeV in Au-Au collisions.
