Strange hadron and resonance production in Pb-Pb collisions at √sNN=2.76 TeV with the ALICE experiment at LHC

The ALICE experiment at the LHC has measured the production of strange hadrons and resonances in Pb-Pb and pp collisions at unprecedented high beam energies. The study of strange hadrons and resonances helps us to understand the properties of the medium created in the heavyion collisions and its evolution. We present the yields (dN/dy) at mid-rapidity for strange hadrons (Lambda, Xi(-), Omega(-), their anti-particles and K-S(0)) and resonances (phi and K*(0)) for several collision centrality intervals. The results from Pb-Pb collisions at root s(NN) = 2.76 TeV are presented and compared to corresponding results from pp collisions and lower energy measurements. Baryon to meson ratios and resonance to non-resonance particle ratios relative to pp collisions are shown as a function of collision centrality and compared with the results at lower energies.
